چکیده
1 Abstract-This paper was written by a Working Group of the IEEE Power System Relay Committee to provide guidance to the industry to better coordinate generator protection with generator control. The paper discusses specific calculation methods that can be used to insure generator protection and excitation system control are fully coordinated. It also specifically addresses the coordination of relays with generator full load capability and machine steady state stability limits. Because of recent blackouts, NERC (North American Electric Reliability Council) is developing standards [1-3] for the coordination of generator protection and control. This paper provides practical guidance on providing this coordination.

Generator Over Excitation Capability and Excitation System Limiters
Sometimes, power system events have shown the need for generators to operate in the overexcited region to support stable operation. Operation up to, and transiently beyond, the overexcited limits from the capability curve is sometimes required. The two main issues in the paper are the generator capability in this region and the design of OEL (OverExcitation Limiters) in the excitation system th...

Nowadays, the generation profile of electric energy systems changes with the increasing integration of renewable energy sources. Wind turbines with Doubly-Fed Induction Generators (DFIG) are replacing bulk synchronous generators. The replacement of these synchronous generators will affect power system dynamics in a large extent. Standard controllers for synchronous generators like governors and...

A battery Energy storage system (BESS) based voltage and frequency controller (VFC), for an Autonomous Asynchronous Generator (ASG) driven by an uncontrolled pico hydro turbine used in constant power mode, is presented in this paper. Excitation of the asynchronous generator with capacitor bank enables it to generate rated voltage at no load. The additional reactive power demand of the ASG on lo...
