针对镇海发电厂４号机组同步器死区大、惯性大、可控性差及控制精度低等问题，采用直接能量平衡控制方式和模糊ＰＩＤ（ＦｕｚｙＰＩＤ）复合控制策略，成功地实现了机组协调控制系统在３％、５％负荷升、降速率下的升、降负荷控制，保证了主蒸汽压力在±０２ＭＰａ范围内波动和负荷的稳定，满足了机组协调控制系统的快速性和稳定性的要求，为电厂安全、经济和稳定运行提供了保证，为实现ＡＧＣ控制奠定了基础。
In view of the large dead zone, large inertia, poor controllability and low control accuracy of the synchronizer of No. 4 unit in Zhenhai Power Plant, the direct energy balance control method and FuzyPID compound control strategy were successfully adopted to realize the unit Coordination of the control system at 3%, 5% load rise and fall speed under the control of drop load to ensure that the main steam pressure fluctuations in the range of ± 0.2MPa and load stability to meet the unit coordinated control system and the rapid Stability requirements, for the safety, economic and stable operation of the plant provides a guarantee for the realization of AGC control laid the foundation.
