摘要
针对出线侧带并联电抗器的大型火电机组进行并网核相试验时遇到的特殊问题,提出了以发电机作为核相电源,进行两待并系统核相的新方法。对试验方案进行仿真模拟,对试验过程中各电量的变化进行考查,并对各设备保护的定值整定和投入进行论证。最后在核相试验过程中采取综合措施顺利解决励磁系统参数配合问题,圆满完成核相试验。
This article presents a new sequence-checking method for a large power plant which has a shunt-wound reactor on the connecting line. By simulating the new method on computer, the change of current and voltage is checked and the equipment protection scheme is elicited. Finally the problem of excitation system is resolved by integrate means , and the phase checking experiment is completed successfully.
