摘要
介绍了M310堆型及其改进型压水堆核电厂的应急柴油发电机定期带载试验方法,分析了该方法存在的问题。根据IEEE387标准提出了应急柴油发电机定期带载试验采用并网试验的方法。修改后的试验方法是否可行取决于中压厂用电系统的短路电流是否超限,为此以方家山核电厂为例对应急柴油发电机并网试验情况下中压厂用电系统的短路电流进行了计算。计算结果表明中压厂用电系统三相短路电流未超限,修改后的试验方法满足相关标准规范的要求。
The periodic load testing method of the emergency diesel generator of M310 nuclear power plant is introduced,and its problems are analyzed.According to standard IEEE387,a modified method is put forward,which allows the emergency diesel generator connected to the grid to perform the periodic load test.The modified method which is feasible or not depends on the short-circuit current of the medium voltage electrical system during the test.That is to say the short-circuit current must not exceed the breaking capacity of the circuit break.The calculation results show that the three-phase short-circuit current of the medium voltage electrical system is not over the limitation,therefore the modified method meets the relevant standards requirements.
