THE ANALYSIS OF THE STABILITY FOR TURBINE HYDRAULIC SYSTEM IN A NUCLEAR POWER PLANT

摘要

In this paper, described about the proceedings from the taking of countermeasure after analysis and maintenance to being able to conduct safety operation for nuclear power plant. The cause of the occurrence of the breakdown because of the increase of the motor electric current in turbine hydraulic oil unit while the 3rd generator at YoungKwang Nuclear Power Plant Normally loaded and turbine system is operated. The turbine hydraulic system at a nuclear power plant is a device controlling the motion and suspension of a motor directly connected with the safety operation of a Generator, and is a core controlling device maintaining the frequency of electric system within a fixed scope.
