摘要
现有的测试手段和方法无法模拟设备在电网中的实际工作状态,需开展供电系统半实物仿真验证,从供电系统电应力的关键影响因素入手,开展电气部件故障层级建模分析,结合供电系统故障统计与分析的结果,确定了浪涌电压、浪涌电流、短路电流和尖峰脉冲电压为测试应力,参照国军标完成了电应力半实物仿真测试环境的搭建,实现了电应力稳态特性和瞬态特性的注入仿真,测试结果同分析结果一致.
Since the existing testing means and method cannot simulate the actual working state of the equipment in the power grid,it is needed to carry out the semi-physical simulation verification of the power supply system.Starting from the key influencing factors of the electrical stress of the power supply system,the fault level modeling and analysis of electrical components are carried out.Combining with the result of the power supply system fault statistics and analysis,the surge voltage,surge current,short-circuit current and peak pulse voltage are determined as test stresses.The construction of the electrical stress semi-physical simulation test environment was completed with reference to the national military standard,and the injection simulation of the steady state and transient characteristics of the electrical stress was realized,the test results are consistent with the analysis results.
