随着发电机容量的不断增加,机组通过发电机逆功率保护动作停机的方式逐渐在许多发电厂得到推广使用。但是发电机组通过程序逆功率保护动作解列停机失败的案例也经常发生,并且在新建大型发电机组的停机应用过程中尤为显现。为保证电厂汽轮发电机组的安全可靠停运,充分发挥发电设备的使用寿命和能效,本文利用Matlab工具,从功率、阻抗角和运行操作流程等,对一次典型的程序逆功率停机事件进行深入剖析,并结合实际给出具体的建议。
隨著髮電機容量的不斷增加,機組通過髮電機逆功率保護動作停機的方式逐漸在許多髮電廠得到推廣使用。但是髮電機組通過程序逆功率保護動作解列停機失敗的案例也經常髮生,併且在新建大型髮電機組的停機應用過程中尤為顯現。為保證電廠汽輪髮電機組的安全可靠停運,充分髮揮髮電設備的使用壽命和能效,本文利用Matlab工具,從功率、阻抗角和運行操作流程等,對一次典型的程序逆功率停機事件進行深入剖析,併結閤實際給齣具體的建議。

With the increasing capacity of generator, the generator reverse power protection unit shutdown has been used widely in many power plants. But the generator reverse power protection action process to jump out of shutdown failure cases are often happened,particularly apparent in the new large generating units shut down the application process.In order to ensure the safety and reliability of the power plant turbine generator outage,give full play to the service life and efficiency of power generation equipment,in this paper,using the Matlab tool,from the power,impedance angle,operation process and other,a typical program reverse power shutdown event is analyzed,combined with the actual specific suggestions.
