| Abstract: | This paper deals with the power system real-time static safety control. Based on the P-Q decoupling principle and sensitivity analysis, a fast algorithm for the improvement of the power system safety is proposed. By the pseudo-inverse method and the P-Q decoupled load flow calculating program, this algorithm is capable of directly calculating the correct values of the effective control variables to be adjusted, such as the rescheduling of the active and reactive power of the generators, shedding of the loads, adjustment of the system voltages and transformer taps. Application of this algorithm to an experimental system shows that it is useful and fast. |
