and trial operation of auromatic generation control (AGC) function for 2×300 MW units in second-phase project of Weihe Power Generation Co Ltd have been presented
and corresponding improvement mesures for solving problems appeared in trial operation being put forward as follows:(1)additionally installing 24VDC signal isolator between DCS and RTU;(2)the 24V power supply provided from RTU being changed from TPS instead;(3)adding a function in DEN to make the function of "velocity limiter"being temporarily shielded before the DCS to remote control DEN;(4)adopting varying parameter control in different load sections;(5)adopting anti-saturation technology in integration;(6)adopting feed-forward control technology etc..
