摘要:
为解决长电缆耐压试验中电抗器组合方案的问题,提出了一种长电缆耐压试验设备参数优选方法。改进串联谐振并联补偿接线方式,考虑了设备约束条件,建立以电抗器组合数量最少的目标函数,得到满足设备约束条件下的品质因数区间,继而从中选择出电抗器最少的组合方式作为最优的试验接线方案,同时得到该方案对应的谐振频率,电抗器电流,变压器高压侧电流,变压器输出电压等优选参数。以两条不同长度的某220 kV电缆耐压试验为案例,通过优选方法得到最佳电抗器组合方案,不仅提高了方案选择效率而且实现了兼具试验成本和品质因数的最佳试验效果,为长电缆耐压试验提供了一种新的设备参数优选方法。
Abstract:
In order to solve the problem of reactor combination scheme in long cable withstand voltage test, a parameter optimization method of long cable withstand voltage test equipment is proposed. Improve the series resonance parallel compensation connection mode, consider the equipment constraints, establish the objective function with the minimum number of reactor combinations, and get the quality factor interval under the equipment constraints. Then select the combination mode with the minimum number of reactors as the optimal test connection scheme, and get the corresponding resonance frequency, reactor current, current at transformer high voltage side, transformer output voltage and other optimal parameters. Taking two 220 kV cables of different lengths as an example, the optimal reactor combination scheme is obtained through optimization method, which not only improves the efficiency of scheme selection, but also realizes the best test effect with both test cost and quality factor, and provides a new method of equipment parameter optimization for long cable withstand voltage test.
