UPFC换流阀模块测试装置的研制及应用

针对新兴的统一潮流控制器(UPFC)工程的分级调试，提出一种自动调试的方法，设计了一种测试装置，专门解决换流阀子模块的工程调试。测试装置由测试管理单元和测试执行单元两部分组成，测试管理单元通过内部分布式总线控制测试执行单元，是测试的核心；测试执行单元包括阀控模拟模块、采集模块和能量控制模块。阀控模拟模块模拟阀控装置的通信协议，控制子模块进行功能测试同时进行状态监测，采集模块采集子模块相关的电压状态，能量控制模块给换流阀子模块进行供电，用于测试子模块的充放电逻辑；测试管理单元配置测试执行单元模拟的阀控协议、子模块的拓扑结构等参数以控制测试的功能和流程，测试管理单元结合采集信息和通信状态信息共同辅助进行测试判断，测试结束给出完整的报告，完成UPFC换流阀子模块的自动调试，工程实际表明该方法完全适用于现场验收测试以及出厂调试的需要。

Research and application of sub-module test device for UPFC converter valve

Aiming at the grading debugging of new UPFC(Unified Power Flow Controller) project, an automatic debugging method is proposed, and a test device is designed to solve the sub-module debugging of converter valve. The test device consists of test management unit and the test execution unit. The test management unit is the core of the test device, which controls the test execution unit through internal distributed bus. The test execution unit includes valve-controlled simulation module, sampling module and energy control module. The valve-controlled simulation module can simulate communication protocol of valve-controlled device and control sub-module to realize function test and state monitoring at the same time. The sampling module acquires the related voltage state of sub-module. The energy control module can control energy output to test the charge and discharge logics for sub-module. The test manager unit configures the parameter, including control protocol and the topologic structure of sub-module to control test function and flow. Combining the sampling information and communication state information, the test manager unit can make test judgment and give the test report at the end of test, so as to complete automatic debugging of sub-module of UPFC project. Engineering practice shows that the proposed method is fully applicable to the requirements of field acceptance test and factory debugging.
