Abstract

A speed signal of governor, which control the output and speed of a generator, is important because a signal failure can be causing the shutdown of a power plant. thus, it is necessary to introduce switching method with two complementary signal. This paper presents a comparative study of speed signal switching methods. One of the Proposed methods has been tested at a power plant in Pukcheju and the approach described here is expected to be of wide applicability.
