摘　　要：巴西美丽山水电经一期和二期2回±800kV特高压直流输电工程送出系统的安控协控装置Master Control(简称MC),实现2个大型水电站、2回特高压直流以及近区交流系统之间的安稳装置动作和协控指令执行,主要目的是确保巴西北部水电能够最大限度地送出以及电网的安全稳定运行。深入分析了MC系统的设计原则、覆盖范围以及动作时序,并根据调试期间美一工程带原安控系统正常送电的需求,提出了针对性的交替隔离措施和系统调试优化试验方案,确保对MC系统全部稳控功能和接口设备进行检验;同时在现场完成了试验方案的实施,确认了MC系统的功能正确,动作结果符合预期,满足投入运行的条件。Brazil’s Belo Monte hydropower was sent out through the two±800kV UHVDC transmission projects.The main purpose of the master control(MC)safety control system,installed for this huge system,is to realize the action of the stability device and the execution of the coordinated control instructions between two large hydropower stations,two UHVDCs and the nearby AC system,to ensure the maximum transmission of hydropower in northern Brazil and the safe and stable operation of the power grid.This article deeply analyzes the design principles,coverage and action sequence of the MC system,and according to the power transmission requirements with the original stability control system of the Belo Monte Bipolar I project during the commissioning period,the targeted alternate isolation measures and the optimization commissioning plans are proposed to ensure all the stability control functions and the interface equipment of the MC system to be tested.The commissioning plan was implemented on the site.The action results were in line with expectations,and the conditions for operation were met.
