6.2. Hydropower Station 6.2.1. Background

In the course of the 1st Field Work, the JICA Study Team visited four hydropower stations, such as Saguling, Cirata, Sutami, Soedirman, and PLN LITBANG, and confirmed the current achievement of Remaining Life Assessment for hydropower stations in Indonesia, especially possibility of non-destructive examination method and possibility of electrical insulation examination for a generator stator in order to reflect technology transfer. Furthermore, Remaining Life Assessment relating to casing stay vane, runner and generator coil, which will be included in technology transfer provisionally were introduced to hydropower stations and PLN LITBANG in parallel with the investigation of needs. The results of investigation are as follows:

(1) Current Achievement of RLA

1) Saguling Hydropower Station Non-destructive examination for a runner and a casing, and electrical insulation examination for a generator coil have not been conducted as well as RLA. A runner was repaired by welding according to need in the course of periodic inspection, but the amount of welding volume has not been managed.

2) Soedirman Hydropower Station Non-destructive examination for a runner and a casing has not been conducted. Electrical insulation examination has been conducted by measuring insulation resistance and tan δ at the timing of periodic inspection. A runner was repaired by welding according to need in the course of periodic inspection and dimension control has been carried out, but the amount of welding volume has not been managed. Technology transfer of RLA was strongly requested by the power station staff because they already recognized the necessity of conducting RLA but they didn’t know how to conduct.

3) Cirata Hydropower Station Non-destructive examination for a runner and a casing has not been conducted. Electrical insulation examination has been conducted by measuring insulation resistance by them and measuring tan δ by LITBANG at the timing of periodic inspection. Partial discharge monitoring has not been conducted because they have no device. RLA has not been conducted.

4) Sutami Hydropower Station Non-destructive examination for a runner and a casing has not been conducted. Electrical insulation examination has been conducted by measuring insulation

resistance at the timing of periodic inspection. A runner was repaired by welding according to need in the course of periodic inspection and dimension control has been carried out, but the amount of welding volume has not been managed. Japanese manufacturer carried out site investigation for a runner, a generator and a control panel in 2004. In the course of the site investigation, non-destructive examination for a runner and electrical insulation examination for a generator coil were conducted. Based on the electrical insulation examination results, RLA was carried out by the manufacturer.

(2) Current Achievement of RLA by LITBANG

LITBANG has already Remaining Life Assessment technology for a thermal power station but not for a hydropower station. And LITBANG showed their interest in RLA for a hydropower station and hoped for technology transfer relating to RLA for a hydropower station.

(3) Conclusion

During the course of the above investigation, RLA by utilization of non-destructive examination and electrical insulation examination has not been conducted for hydropower stations. But the necessity and effect of conducting RLA were well understood and they showed their high interest in RLA. The application of RLA to old hydropower stations are well expected to contribute to prevent serious accidents by preventive maintenance.

Based on the above conditions, technology transfer for RLA, by using non-destructive examination method and electrical insulation examination for a generator stator aiming the establishment of preventive maintenance, is to be conducted. The following three (3) topics for the technology transfer were confirmed by the discussion with the Indonesia side and the Study Team in the 3rd Field Work based on the results of the 1st Field Work. - Remaining Life Assessment by using non-destructive examination results for a casing

and a stay vane - Remaining Life Assessment by using the management of welding volume for a turbine

runner - Remaining Life Assessment by using the results of electrical insulation examination for a

generator stator

Since all of the above topics requires the relevant measurement and testing devices, the technology transfer by using devices were not planned and the introduction of the relevant papers were planned firstly. Once the relevant devices will be available in Indonesia in the future, the technology transfer to be conducted by the Study Team helps them brush up their technical capacities to the degree of conducting the testing and judgment by themselves. To achieve the above purpose, the relevant results of measuring and testing done by the

6 - 21 Final Report


KANSAI Electric Power Co., Inc. and the latest papers were to be collected.

However, PDM (On-line Partial Discharge Monitoring) was determined to be demonstrated as one of the facility assessments for a generator stator coil in response to Indonesia’s request raised in the 2nd Workshop.

6.2.2. Technology Transfer 6.2.2.1. Content of Technology Transfer

In the 4th Field Work, the technology transfer relating to the following three topics for hydropower stations and the PDM demonstration at Cirata Hydropower station were conducted.

(1) RLA by using the non-destructive examination results for a casing and a stay vane The RLA is to evaluate the remaining life by firstly modeling the defects resulting from an ultrasonic defecting device as one of the non-destructive method, and by application of fracture mechanism considering the operating stresses and material characteristics secondly. The concrete evaluation method and points to remember were explained by using the actual samples in the technology transfer.

(2) RLA by using the management of welding volume for a turbine runner

The RLA is to evaluate the remaining life of a runner by digitalizing the damage, utilizing an evaluation standard, caused by the repair works for a runner, such as welding volume, stress relief, and deformation. The concrete evaluation method and points to remember were explained by using the actual samples in the technology transfer.

(3) RLA by using the results of electrical insulation examination for a generator stator coil

The RLA is to evaluate the remaining life of a stator coil by estimating the dielectric strength resulting from the measurements of the maximum partial discharge and tan δ carried out for an electrical insulation examination for a generator stator coil. The concrete evaluation method and points to remember were explained by using the actual samples in the technology transfer.

7. CONCLUSION AND RECOMMENDATION In the course of the one-year Study, the Study team visited sixteen (16) power stations, LITBANG, Suralaya Training Center, P3B and local dispatching center in Java-Bali region and collected a lot of relevant data/information in the meetings relating to power generation facilities and O&M. Further more, technology transfer relating to Remaining Life Assessment was also conducted including the demonstration at Cirata hydropower station and Muara Karang thermal power station. Addition to the above activities and studies, three (3) Workshops and three (3) Steering Committees were held and useful comments were made by the participants. Based on the above activities and studies, the following conclusions and recommendations are induced. Table 7-2 shows the summary of objective power stations in respect to their operation and maintenance performance. 7.1. Conclusion 7.1.1. Thermal Power Stations

(1) The Study Team analyzed the operation performance on June 20, 2005 which caused the serious power supply shortage in Java-Bali region, for the objective power stations. The results of analyses are; (a) About 25 % of the total installed capacity with 12,660 MW were forced to stop the

operation and causing the derating due to planned outages and forced outages. (b) The derating caused by fuel issues was about 6 %. The 6 % doesn’t include

shutdown of power station due to the stop of fuel supply.

(2) Concerning the gas and oil related, it is confirmed that MEMR is a regulator and a policy maker, and BPMIGAS (Executive Agency for Upstream Oil and Gas Business Activity) under the direct control of the president is a regulator and a supervisor relating to the gas and oil business.

(3) Development of new coal fired power plants with the total capacity up to 10,000 MW through out Indonesia for the next three years aiming the energy diversification was announced on May 22, 2006 by PLN during the Study Period. According to a newspaper, the development of new coal fired power plant seems more likely to affect the current thermal power stations in some form, especially HSD firing power stations.

(4) The Study Team analyzed accidents and troubles (times and hours) for 75 units among the objective thermal power stations from 2003 to 2005. The results of analysis are; (a) The number and hours of forced outages show the tendency to increase of forced

outage as a whole.

7 - 1 Final Report


(b) The main cause of forced outages is due to the defect or malfunction of Instrumentation and Control (I & C), which might be caused by maladjustment at the periodic inspection, aged deterioration and sometimes by human errors.

Based on the above analysis, measures for “Improvement to preventive routine accidents and troubles” and “Improvement of scheduled inspection work from operation aspect” are prepared by the Study Team.

(5) It is confirmed that PLN’s affiliated companies IP and PJB report their financial status to PLN but don’t submit the accident reports to PLN. And it is also confirmed that MEMR, the control authority for the power sector, is not normally engaged with the electricity related accidents except for the case, such as the large area blackout in Java-Bali region which occurred on August 18, 2005 causing the serious social impact and MEMR has been investigating the cause of and responsibility for the blackout.

(6) In respect of maintenance system for a power station, it is confirmed that IP adopts the Maintenance System Based on Location of Facilities and PJB adopts the Maintenance System Based on Category of Maintenance Methods, and both maintenance systems are different.

(7) It is confirmed that currently Suralaya, Muara Karang, Paiton and Saguling power stations are under procedure of JBIC export credit. Addition to the above four (4) plans, it is also confirmed that PLN has intention to carry out further rehabilitation and modification plans for Suralaya unit 3 and unit 4, and Muara Karang PLTU unit 4 and unit 5, which are excluded in the current JBIC export credit due to the limit of PLN budget.

(8) The Study Team proposed the repowering plans for Tambak Lorok, Grati and Gilimanuk power stations to be converted from the existing PLTU/PLTG to PLTGU. Along with the repowering plans, oil reduction plans are also proposed for UBP basis, such as UBP Semarang, UBP Perak/Grati and UBP Bali.

(9) The economic and financial analyses were conducted for the six (6) proposed plans. The economic analysis resulted in good EIRR exceeding the social discount of 12 % under the current high fuel oil prices. However, the financial analysis resulted in pessimistic project FIRR below the opportunity cost of 12 %. Measures to implement the proposed plans are presented by the Study Team.

(10) The Study Team conducted scoping for the six (6) proposed plans from the viewpoint of Environmental and Social Consideration. And a draft KA-ANDAL is prepared by the Study Team.

Final Report 7 - 2


7.1.2. Hydropower Stations

(1) Regarding four (4) hydropower stations, no derating was observed. Operation and maintenance are well managed.

(2) Some rehabilitation/modification plans for Saguling, Cirata, Soedirman and Sutami were proposed by the Study Team.

(3) The water quality deterioration in the reservoir, due to the inflow of domestic wasted water and factory effluent, is causing the serious damage to the water cooling system at Cirata and Saguling hydropower stations. It is confirmed that Replacement of water cooling piping is under progress at Cirata by PJB own budget or planned at Saguling by JBIC export credit.

(4) It is confirmed that reservoir operation rule for Saguling and Cirata is developed by the Coordination Committee and the generation use of the Citarum River is set at the lowest priority among the utilizations of the Citarum River.

7.1.3. Power Facilities (Transmission Line and Substation)

(1) Construction of southerly 500 kV transmission line with two circuits was completed in June 2006.

(2) It is confirmed that in 500 kV transmission line, only the section which is restricted by system stability is not satisfied with N-1 criteria and as for 500/150 kV transformers, the ratio of transformers whose availability is over 60 % accounts for 90 % or more of the total, and almost of transformers do not meet N-1 criteria.

(3) The Study Team analyzed the accidents relating to transmission lines and transformers. The result is that the number of service interruption due to transmission line is small, but one due to transformer faults has been increasing year by year.

(4) It is confirmed that generators owned by IP and PJB do not carry out governor free operation even though Grid Code regulates all power stations have to be operated with governor free mode. It is also confirmed that generators owned by IPPs and PLN (Muara Tawar) are operated with governor free mode.

7.1.4. Technology Transfer for Remaining Life Assessment (RLA)

(1) It is confirmed that LITBANG, PLN’s research institute, has many experiences in RLA for boiler related, while RLA for turbines and generators is conducted by manufacturers, and RLA has not been conducted by Indonesia side for hydropower stations.
