摘要
当前电网正开展统一调频市场建设,在实际电网中开展自动发电控制(automatic generation control,AGC)功能测试的难度将进一步加大,调度自动化迫切需要有一个可真实模拟实际电网的仿真环境来支撑开展AGC功能测试。实时仿真在技术可行性上具备开展AGC闭环测试的能力,为验证其有效性,本文搭建了基于实时仿真的AGC闭环测试系统,反演了实际现场的AGC动作事件。试验结果表明建立的RTDS实时仿真模型具备仿真大电网系统频率变化的能力,同时RTDS系统具备与AGC应用闭环试验的能力,可应用于电网AGC功能测试工作。
At present,the power grid is carrying out the construction of unified frequency modulation market,and the difficulty of automatic generation control(AGC)function test in the actual power grid will be further increased.Dispatching automation urgently needs a simulation environment that can simulate the actual power grid to support the AGC function test.Real time simulation has the ability to carry out AGC closed-loop test in terms of technical feasibility.In order to verify its effectiveness,this paper builds a AGC closed-loop test system based on real-time simulation,and inverses the actual AGC action events in the field.The test results show that the RTDS real-time simulation model has the ability to simulate the frequency change of large power grid system,and the RTDS system has the ability to apply the closed-loop test with AGC,which can help the AGC function test of power grid.
