【Abstract】 A novel real-time simulation based closed-loop detection method for automatic voltage control(AVC) system of regional power grid is proposed. Based on the proposed method a detection platform for the AVC system, which is composed of real-time simulation system, intermediate data conversion interfaces and AVC system, is built. The system model constructed in the real-time simulation system contains system platform model and central control system model, and transformed by intermediate data conversion interfaces the AVC system, the analog quantity and switching values of real-time simulation system are transmitted to the AVC system, and through the computation of AVC system the obtained control strategy is transmitted back to real-time simulation system via intermediate data conversion interfaces. The proposed closed-loop detection platform provides a solution to the field-testing for AVC system of regional power grid, and the objective of detecting AVC system of regional power grid in labor is realized.更多还原
