摘要： A desired value of reactive power flow between a to-be-controlled power system and an adjoining power system is determined according to measured values of the reactive power flow and an effective power flow and desired voltage values of the to-be-controlled power system and of the adjoining power system. Thereafter, a required value of a reactive power of the to-be-controlled power system is calculated according to the desired value of the reactive power flow, the measured values of the reactive power flow and the effective power flow, and the desired voltage value and a measured voltage value in the to-be-controlled power system. Thereafter, a control apparatus having an electric capacity near to the required value of the reactive power is selected from control apparatus arranged in the to-be-controlled power system to make the selected control apparatus adjust a voltage of the to-be-controlled power system. Therefore, cooperation of the to-be-controlled power system with the adjoining power system can be performed by collecting locally-existing-information, and a voltage fluctuation and/or a reactive power fluctuation in the to-be-controlled power system can be immediately suppressed.

摘要： A voltage stability discriminating system for a power system is disclosed for calculating a multiple load flow solution relating to a voltage stability discrimination for a power system in which the voltage stability can be discriminated fast and accurately due to the fact that the voltage stability discrimination system of the power system is constructed such that the multiple load flow solution is estimated in advance during a calculation process of the load flow calculating means. For example, the load flow calculation is made through the N-R method of a rectangular coordinates system, and after the first solution is converged and the first load flow solution (an output value of the load flow calculation means) is determined, the estimated value of the above-mentioned multiple load flow solution is examined by the load flow solution determining means so as to determine the first load flow solution as the load flow solution, or the estimated value of the above-mentioned multiple load flow solution is applied and the load flow solution is determined by performing the load flow calculation.
