接力式馈线自动化测试方法研究与应用
|
摘要
在现有馈线自动化仿真测试方案的基础上,引入电力系统暂态仿真软件PSCAD/EMTDC,通过PSCAD/EMTDC接口模块开发实现了其与现有馈线自动化测试平台的数据同步,进而构成了实时闭环的高保真仿真测试系统。通过PSCAD/EMTDC仿真得到的电流电压可以实时地注入到配电自动化主站或配电终端中,同时被测系统的开关状态也同步地反馈到PSCAD/EMTDC中。新的测试方法可以逼真地模拟配网系统各种运行工况和故障形态,尤其是实现了对接地故障的仿真测试。应用新的测试方法对智能分布式馈线自动化系统进行了测试,实际验证了新方法的可行性。
Based on the existing test solutions of feeder automation,the transient simulation software PSCAD/EMTDC of power system is employed to integrate with existing test platform to form a closed-loop test bench by the developing of user defined function modules. To streamline data exchange among PSCAD/EMTDC,test platform and DTU,a data relay method is used. The currents and voltages obtained from PSCAD/EMTDC can be injected into master station or DTU,meanwhile,the switches state of tested distribution network shall be updated in PSCAD/EMTDC accordingly. The new test method could simulate various operation conditions and faults,especially for the earth fault. The new method has been applied to a testing smart distributed FA system,and the results demonstrate the feasibility of this method.
