Regional Control Center (RCC) Jamshoro

RCC Stands for Regional control center. Regional Control Centre at Jamshoro is charged withMonitoring and control of regional power System of the network for interiot sindh . The mainfunctions of these Power Control Centres is given below:

1. Real time control of the load generation, power exchanges, voltage regulation, generation reservesand the transmission network;

2. Follow up of efficiency, fault analysis, compilation of statistics, reporting and accounting;

3. Short and long term planning, including load prediction, and generators, schedules, power balanceplanning, coordination of unit out-ages for maintenance and planning for reserves;

4. Arranging of routine and emergent shortdowns on generators, transmission lines, powertransformers and other components of the power system.

With the passage of time, most of the equipment has become obsolete and its capacity is notsufficient to control expanding power grid system and require up-gradation.

Main components of RCC includes the following

1.Supervisory Control & Data Acquisition (SCADA)

2.Energy Management Sysetm (EMS)

3.Remote Terminal Units (RTUs)

4.Mimic Board

1.Supervisory Control & Data Acquisition (SCADA): Supervisory control and data acquisition (SCADA) systems have traditionally played a

vital role by providing utilities with valuable knowledge and capabilities that are key to aprimary business function - delivering power in a reliable and safe manner. A quality SCADAsolution is central to effective operation of a utility's most critical and costly distribution,transmission, and generation assets. One of key processes of SCADA is the ability to monitor anentire system in real time.This is facilitated by data acquisitions including meter reading,checking statuses of sensors, etc that are communicated at regular intervals depending on thesystem.A well planned and implemented SCADA system not only helps utilities deliver powerreliably and safely to their customers but it also helps to lower the costs and achieve highercustomer satisfaction and retention.There are many parts of a working SCADA system. A SCADA system usually includes signalhardware (input and output), controllers, networks, user interface (HMI), communications

equipment and software. All together, the term SCADA refers to the entire central system. Thecentral system usually monitors data from various sensors that are either in close proximity oroff site (sometimes miles away).For the most part, the brains of a SCADA system are performedby the Remote Terminal Units (sometimes referred to as the RTU).

Critical Functions of SCADA: Following functions are carried out every 2 seconds : Switchgear Position, Transformer taps, Capacitor banks Tie line flows and interchange schedules Generator loads, voltage etc., Verification on links between computer and remote equipment

3.Energy Management system:Energy management includes planning and operation of energy-related production and

consumption units. Objectives are resource conservation, climate protection and cost savings,Energy Management encompasses a wide range of activities and expertise in the optimal use ofenergy.This includes the areas of:1) Development of management strategies programmes and plans,2) Implementation of techniques, technology and tools3) Measurement, verification and control.

3.Remote Terminal Units (RTUs): A remote terminal unit (RTU) is a microprocessor-controlled electronic device that

interfaces objects in the physical world to a distributed control system or SCADA (supervisorycontrol and data acquisition) system by transmitting telemetry data to a master system, and byusing messages from the master supervisory system to control connected objects. The RemoteTerminal Units consists of a programmable logic converter. The RTU are usually set to specificrequirements,However, most RTU allow human intervention, for instance, in a factory setting,the RTU might control the setting of a conveyer belt, and the speed can be changed oroverridden at any time by human intervention. In addition, any changes or errors are usuallyautomatically logged for and/or displayed.
