Project news

Modern monitoring of substations installed at Itaipu Binacional, Brazil/ParaguayABB delivered a comprehensive system for the monitoring of switches, breakers and transformers of substations to the water power plant Itaipu Binacional, the second largest hydroelectric plant in the world. The power plant is located in South America on the border between Brazil and Paraguay and is very important for the electricity demand of both countries.

For the monitoring of substations Itaipu needed a comprehensive system which should be able to handle different protocols. As a must, the communication between the field and the control center is to be handled via the standard protocol IEC 61850. Furthermore, an integrated human machine interface (HMI) is needed for diagnostics and prognostics. Besides a competitive price for the complete system, all solutions have to be fully certified.

As a solution ABB provided an integrated monitoring system for the breakers, disconnectors and power transformers. The scope included 126 pieces of the compact and flexible 560CIG10 of RTU540 product line, PLC devices with a high process data speed and, as a supervising system with HMI, MicroSCADA pro.

The customer appreciated the solution by ABB since all specifications were met. Additionally, the compactness of the RTU540 allowed the set-up in each section on the field together with switches, breakers and transformers.

Besides the reasonable price, the RTU 560CIG10 fulfilled all requirements for the application as IEC 61850 server, underlining its interoperability with third-party devices. Within this project this advanced protocol converter function refers to IEC 61850, IEC 60870-5-104, Modbus and DNP3.0.

The water power plant Itaipu located on the Paraná river has an installed capacity of 14000 MW. The storage lake has a volume of up to 29 billion m3 with a surface of 1350 km2, which is more than twice the size of the Bodensee in Europe. The output of the water plant covers 17% of the electricity demand of Brazil and 72% of the demand of Paraguay. Since Paraguay does not require all the electric power, it exports parts of it to Brazil and offers free power to foreign investors. In 2012 the complete Itaipu complex produced enough power to meet all of Paraguay‘s power needs for nine years, or the entire planet for two days.

Standardized and automated hydropower for reliable energy supplyFor the automation of several small hydropower plants in Guatemala ABB’s certified partner COMCARSA delivered a complete protection, control and supervision panel.

The hydropower plants generate an essential amount of energy for the region, therefore the reliable operation of the plants is necessary. As the small dams at each plant can hold only a small amount of water for the impulse of the turbines, the current water level has to be precisely monitored and controlled to ensure a reliable system operation.

For the modernization and automation of the hydropower plants ABB and COMCARSA provided several RTUs which were installed in the substation and at the dams. In the substation the small and efficient 560CIG10 which offers high functionality in a compact design handles the communication with the IEDs, the automatic voltage regulator and the RTUs in the field via IEC 61850 and Modbus. Furthermore, the communication to the control center is handled via DNP3.0. In addition, the integrated I/Os of 560CIG10 collect the data from the turbine devices. The implemented PLC programming enables operation sequences customized to the restrictions of the hydropower plants. The RTU PLC implementation covers the start and stop of the generator, the load regulation based on the available water in the reservoir and the reactive regulation around the set point.

In the field the installed 560CIG10 measures the water level at each dam and reports the data to the RTU in the substation. Additionally, the RTU also handles the control of the valves and reports the status to the substation. The collected variables include temperature and pressure, injectors position, oil level, filter status, motor start confirmation and bypass position as well as emergency stop. Records of the collected information is also processed and stored for future reference.

Successful automatic network reconfiguration at Split airportTo handle the increasing number of passengers one of the most important airports in Croatia succeeded in a reliable and efficient power supply for the complete network. For this, our external partner Koncar set up a retrofit project which took 4 months during winter season, a time where the airport is frequented by smaller number of passengers.

The power grid of the airport is supplied via two substations whose equipment was old and not fit to balance the energy needs. Furthermore, manual onsite operation was required in case a power failure occurred. Therefore the availability of the local operations team affected the reaction time heavily, with the most problems during holiday seasons.

To underline the importance of Split airport, Koncar provided a complete solution for the upgrade of the complete power grid. First, the primary switchgear consisting of 2 substations was retrofitted with new equipment. Furthermore, to enable remote control and supervision, ABB’s RTU540 with remote input/output (I/O) modules and PLC functions according to IEC 61131 were installed. Measuring power, energy, power factor and frequency as well as power values (W, VA, VAR) within the network are now possible with the newly installed multimeter 560CVD03. The automatic reconfiguration of the power grid was achieved with the implementation of an advanced algorithm.

With this new system and the reliability of power supply the customer is very happy. The remote and local monitoring and control of the substation manual onsite operations are not necessary anymore. Power outages can now be detected on the incoming feeders so that affected areas can be isolated quickly. In addition, fault detection, localization and isolation within the substation enable the airport to adapt quickly to changes to avoid power outages. Thus, in comparison to the old system, the average power outage time could be lowered to less than 3 seconds which contributes significantly to the higher safety of the air traffic.

The automation and standardization of the system brought along many advantages for the customer. Thanks to the remote access through standard protocols problems within the network can be quickly detected and restored. The compact system minimized the field control wiring and the start-up times. Furthermore, the availability of the HMI at the main plant is secured. Further extensions can be easily implemented into the new system. The modern and easy-to-understand equipment also enables the companies operating the generation complex to work with only minimal training.

Product manager Christian Glocker explained the features and advantages this integrated solution offers for station monitoring with RTU560 product line. When it comes to the upcoming cancellation of support for Windows XP this PC module provides an easy and convenient way to have the integrated HMI available without any external PC or laptop in the station.

Global product manager Sigbert Reimann summarized the latest RTU developments and gave an overview of the future releases. As a highlight, the upcoming release of the new RTU520 product line raised a lot of interest. In the exhibition area participants could also get an insight into this future product line.

RTU migration solutions were presented by Reza Khalili, responsible for service and support in the RTU team. Based on his informative demonstration on how ABB protects the investments of its customers two reference cases about the upgrade from RTU211 to the cost-efficient RTU511 with additional functionalities showed the effectiveness and benefits of the migration for customers. Our sales representative from South Africa, Bruce Webster, highlighted the successful migration of RTU211 to RTU511 in two interesting reference cases from Zambia and Botswana. Another successful implementation was explained with the reference case from a German utility.
