Implementation of automatic frequency control system at samanalawewa power station

By EGU Subhashana


Electricity cannot be stored, what is produced has to be consumed immediately. The frequency control theory is used for balancing the power system; it means electrical energy should always be equal to summation of demand and system losses. Samanalawewa Power Station where the frequency control system is operated manually has experienced the need of an automatic frequency controlling system. Therefore a microcontroller based automatic frequency control unit is used to correct the errors mainly due to human factors and also it is more accurate than manual system and gives lot of benefits. Finally it saves the valuable time and money to the public. Therefore automatic frequency control system is essential. The system basically composes with a microcontroller, an LCD Display, Relays and a Selector switch. This report describes the theoretical background on frequency control, concepts and implementation, about the microcontroller, preparation, software installation and programming, Result interpretation and finally the conclusion of automatic frequency control to be implemented at the Samanalawewa Power Station
