葛洲坝二江电厂自投产发电以来,发电机励磁系统经历了晶体管集成电路 PI 励磁调节器、微机型 PID 励磁调节器、微机型线性最优励磁控制器3个阶段,这3阶段中包括两次大的设备改造。目前二江电厂7台机组励磁调节器全部改造为微机型线性最优励磁控制器。经过近10年的技术改造和设备换型,二江电厂发电机励磁系统自动化程度和可靠性等 Gezhouba Erjiang Power Plant since put into operation since the generator excitation system has experienced a transistor integrated circuit PI excitation regulator, microcomputer PID excitation regulator, microcomputer-based linear optimal excitation controller three stages, the three stages include two Sub-large equipment transformation. At present, Erjiang Power Plant 7 units excitation regulator all transformed into microcomputer-based linear optimal excitation controller. After nearly 10 years of technological innovation and equipment replacement, Erjiang power plant excitation system automation degree and reliability
