TURBINE CONTROL SYSTEM APPARATUS WHICH IMPROVES STABILITY BY CONTROLLING AN OPENING VALVE IN CASE OF NETWORK SYNCHRONIZATION AND CONNECTION OR NETWORK SYNCHRONIZATION AND RELEASE AND A METHOD THEREOF

摘要

PURPOSE: A turbine control system apparatus and a method thereof are provided to prevent an electric generator from becoming a synchronous motor by using a speed controller and a generator output controller, and to guarantee a rated speed.;CONSTITUTION: A turbine control system apparatus comprises an inflow steam opening valve(100), a turbine(200), a generator(300), a first switch(500), a second switch, and a turbine control device(400). The first switch is opened/closed for produced electric power to be synchronized and connected in a network. The second switch is opened/closed to supply electricity to power plant instruments. The turbine control device includes a speed control unit, a generator output control unit, an opening demand information calculating unit, and an opening control unit; receives the status information from the turbine, the generator, and the first and the second switch; and controls the inflow steam opening valve.;COPYRIGHT KIPO 2013;[Reference numerals] (200) Turbine; (300) Generator; (AA) Steam; (BB) Control valve; (CC) Turbine speed information; (DD) Opening demand; (EE) Speed error information; (FF) Output demand information; (GG) Speed control unit; (HH) Power generator output control unit; (II) Power generator output information; (JJ) Sub-transformer; (KK) Main transformer; (LL) System; (MM) Transformer for connection; (NN) Driving transformer; (OO) Power generator device
