Abstract

As an alternative to converting a brushless exciter to static excitation in order to improve an exciter’s response time, conversion of the existing conventional brushless exciter is possible. A high initial response (HIR) brushless excitation system has the ability to force its output to ceiling voltage in 0.1 second or less, which is a response time similar to a static excitation system. To achieve the required fast response time, various modifications to the existing exciter components are required, including the ac exciter stator, permanent magnet generator (PMG), and voltage regulator. This paper describes those required modifications and associated technical information. This paper presents a concept solution that decreases the response time of a brushless exciter in order to respond to grid disturbances via the excitation system, while minimizing modification of the existing excitation system configuration.
