基于功率传输转移分布因子的简化电网潮流计算方法
为了减少大型电力系统的潮流计算时间,研究简化电网的潮流计算方法具有重要意义。现有方法将传统Ward等值技术用于电网简化后,简化电网却产生与原始电网不同的潮流结果。针对这种情况,提出了一种改进的简化电网的直流潮流计算方法。在已有研究的基础上,给出了基于功率转移分布因子的直流潮流算法以及使用Ward技术对电网的简化方法。结合上述两部分,给出了基于功率转移分布因子的简化电网潮流计算方法。通过仿真算例表明,所得的结果具有较高的精度,可用于简化大型电网的潮流计算、潮流预报等应用中。...

| Notes | YIN Zili, CHEN Yuxing （Fujian Electric Power Co., Ltd., Fuzhou 350003, China） power transfer distribution factor; reduced power grid; DC power flow; Ward; power flow forecast In order to reduce the time of large power system power flow computation, the study of power flow computation method for reducing power grid is much more significant. But, the existing method of Ward is used to the reduce grid and different result as the original grid is got. Aiming at this condition, an improved DC power flow computation method is presented in reduced power system. Based on the basis of present study results, the DC power flow computation method based on power transfer distribution factor is deduced. The Ward technology is used to reduce the power grid. Combining with the two parts, the power flow computation method for reduction grid based on power transfer distribution factor is given. Simulation results show that experimental result has high precision, and it can be applied in the power flow computation for the reduced |
