【Abstract】 The synchronous phasor measurement unit (PMU) based on global positioning system (GPS) which can directly measure the nodal voltage phasors is a new type of measurement device. According to the concept of direct solvable power flow the optimal configuration of PMU by genetic algorithm (GA) is proposed. The construction of the mathematical model of GA, i.e., the evaluation function,is always the bottleneck in its application. Here, the mathematical model with optimal configuration of PMU is established and taking this model for evaluation function the corresponding GA is developed. The results of calculation examples show that the established model and the developed algorithm are effective.更多还原
