Wykorzystanie pomiarów synchronicznych do realizacji obszarowej automatyki odciążania

In the article chosen aspects of Wide Area Control System (WACS) are described. Some limitations of load sheding systems based on local signals are presented. Description of load sheding systems in some characteristic conditions of electro power systems is provided. A concept of adaptive load sheding system based on the balance of network area with synchrophasor technology utilized to define additional decision criteria is proposed. This concept allows the implementation of the new functions which are difficult or impossible to create by classical local automation. The problems with sensitivity on some disturbing signals of standard frequency estimation algorithms are discussed.
