中文摘要:多配网环境中存在电压幅值低、电子传输时间长的现象,为解决上述问题,提出新型多配电网线路并发合环电压差计算方法。按照配电网的网架规划情况,对电路元件进行选址定容处理,实现线路的整体负荷预测,完成多配电网线路环境的重构操作。在此基础上,处置电网环境中的并发分闸节点,并根据合环等效模拟结果,计算电网线路的正弦稳态值,实现多配电网线路并发合环电压差计算方法的顺利应用。对比实验结果表明,与常规空载电压差计算手段相比,应用新型并发合环电压差计算方法后,多配网环境中的电压幅值稳步提升,电子传输时长也明显降低。

Study on the Calculation Method of Concurrent Closed Loop Voltage Difference for Multiple Distribution Network Lines
Abstract:The phenomenon of low voltage amplitude and prolonged time of electronic transmission exists in the multi-distribution network environment. To address this problem, a new method for calculating the voltage difference of the concurrent closed loop for multiple distribution network lines is proposed in this paper. According to the grid planning of the distribution network, the circuit components are selected for site and capacity determination, the overall load prediction of the line is realized, and the reconstruction of the multi-distribution network line environment is completed. On this basis, the concurrent shunt nodes in the grid environment are disposed, and the sinusoidal steady-state value of the grid line is calculated according to the equivalent simulation results of the closed loop, so as to realize the smooth application of the voltage difference calculation method of the concurrent loop of the multi-distribution network line. The experimental results show that, compared with the conventional no-load voltage difference calculation method, the voltage amplitude in the multi-distribution network environment increases steadily with the application of the new concurrent closed loop voltage difference calculation method, and the electronic transmission time also decreases significantly.
