基于虚拟故障端口法推导了考虑线路对地电容及多回互感情况下虚拟端口参数的计算公式,给出了考虑变压器相移的故障电压、电流的分布计算方法,在此基础上开发了一套故障计算程序,并应用于整定计算系统中。结果表明该方法具有较好的计算速度和准确度,是一种有效的故障计算方法。
Based on the virtual fault port method, the calculation formula of the virtual port parameters considering the capacitance of the line to the ground and the mutual inductance between multiple circuits is deduced. The calculation method for the distribution of fault voltage and current considering the phase shift of the transformer is given. Based on this, Fault calculation program, and used in setting calculation system. The results show that this method has a good calculation speed and accuracy, is an effective method of fault calculation.
