PST型变电站综合自动化系统测试仪的研制

Research and development of test equipment typed PST for substation integrative automation system

PST型变电站综合自动化系统测试仪主要由人机接口模块、主控模块和功率源模块组成。信号源每周波拟合的波形点数高达30000点,波形保真度高,输出无需低通滤波器,从而具有很好的暂态特性、相频特性、幅频特性,能实现变电站综合自动化系统的同期功能测试、遥测精度校验以及系统性能指标测试等功能。

The PST-type test equipment consists of man-machine interface module, main control module and precise power sourse module. The dots which are composed in each cycle are up to 30,000.High fidelity is gueranteed, and a wavefilter is not required for the output, as a result, this test equipment has some remarkable characteristics,such as transient character- istic, phase frequency characteristic,and amplitude frequency characteristic.Further more,a multi-functional target can be achieved with the use of this equipment,such as, the test of the synchronism function of the substation integrative automation system, the calibration of the data acquisition and tests of the performance index of the substation integrative automation system.
