Applied Researches For ANHUI Electric Power Based On Advanced Digital Power System Simulator(ADPSS)

During "Twelfth Five-Year Plan" period, Anhui power grid load demand, the rapid growth of the power installed capacity is also increasing year by year. At the same time,1000kV UHV, smart substations have been put into operation in a variety of automatic safety devices in the grid makes the grid operation control becomes very complicated. In this study, and strive to the use of advanced simulation tools and devices, Anhui power grid operation, analysis, control and provide quality technical support and solutions.In2008-2009, AEPRI completed a collaboration with CEPRI to establish Anhui power grid all-digital real-time simulation the system construction (ADPSS,). On this basis, I and my team to carry out a large number of protection devices, excitation equipment, security and stability of the device applied technology research.Mainly the following aspects:1. The establishment of Anhui entire network electromechanical transient model and the local area grid electromagnetic transient model. And electromechanical transient model for electromagnetic transient model hybrid simulation connection.2. The establishment of Anhui power grid real-time digital simulation platform. Use the ADPSS simulation system and the physical interface box and power amplifiers, and establish a closed-loop test system.3. Carry out inspection and testing of applied research of220kV transmission line protection devices. Anhui power grid transmission line protection, digital dynamic simulation test results confirm that the test platform that is fully able to meet the real time dynamic simulation of rapid response unit protection.4. Carry out the excitation system simulation technology of the digital to analog closed-loop test environment. A large number of simulation results show that real-time digital platform based on the electromechanical transient simulation environment to meet the response on the grid in real-time dynamic simulation of the slower device in the mode of the whole network.5. Cany out the power grid safety auto (Experimental Application of security stability control) device coordination and control strategy.This article summarizes the findings and points out that the further prospects and ideas of the research work carried out in the direction of this study.
