    This paper addresses a technique to solve the problem of accumulated heat transfer in solenoid coil of the solenoid valve controlling hydraulic damper by using the switching technique with low frequency. This new method can result in saving the energy loss in solenoid coil. In addition, this technique aims to solve the fundamental problem by reducing direct heat transfer in solenoid coil of the solenoid valve and protecting complete gas turbine trip from the hydraulic damper closing failure and heat recovery steam generator (HRSG) trips from burnt solenoid coil of hydraulic damper. For this experiment and research, the data was collected from South Bangkok Combined Cycle Power Plant Block II. After using low frequency switching circuit technique the gas turbine trip as well as the HRSG trip did not happen. © ICROS.

    This paper is to mention to the case study of protecting gas turbine trip from damper closing failure and heat recovery steam generator (HRSG) trip from solenoid coil of hydraulic damper burnt. The prevent maintenance method on the most frequent events that trip the gas turbine and HRSG and how to protect the recurrence is also described. © 2006 ICASE.
