【Abstract】 The structure of AGC in Shanghai Power Grid and CCS in the power plant are described. The main problem during AGC system operation in Shidongkou No.2 Power Plant is the time lag is too long between load command and load response, thus produces a certain over regulation and corresponding improving measures such as enhancement of the reliabity of main equipments and auxilliaries and revision of controlling logic are needed to improve the regulating quality of CCS.更多还原
