Embodiment Construction

[0065] Below in conjunction with the accompanying drawings, taking the 20MVA flexible DC transmission demonstration project of Shanghai Nanhui Wind Farm jointly developed by MMC-HVDC Project-China Electric Power Research Institute and Shanghai Electric Power Company as an example, the specific implementation of the present invention will be further described in detail

[0066] This embodiment provides a joint test method of a flexible direct current transmission dynamic simulation device and an engineering control system. The feature of this method is that the actual 10MVA-100MVA level project's conversion is carried out through the dynamic simulation test device of the flexible direct current transmission system (the system is based on the modular multilevel voltage source converter direct current transmission system (MMC-HVDC)). The station-level control system conducts a real-time closed-loop test. It is characterized in that the method can verify the control system's seque...

Abstract

The invention provides a combined test method of a dynamic simulation device and an engineering control system. The method is characterized in that: through a dynamic simulation device in a flexible direct current power transmission system, carrying out a real-time closed-loop test on a converter station level control system of a direct current power transmission systems engineering of an actual modular multilevel voltage source transverter, wherein adjusting a parameter of the dynamic simulation device is included; carrying out converter valve unlocking and locking tests of the dynamic simulation device; carrying out starting stopping flow tests of an engineering control system; carrying out power-fail recovery tests of the engineering control system and the dynamic simulation device; carrying out a zero load adjusting test of the control system; carrying out a dynamic simulation device with a passive load test with the control system; carrying out an STATCOM operation mode combined test with the control system and the dynamic simulation test device. According to the invention, an operation mode of engineering is simulated, dynamic response of an MMC transverter and alternating current and direct current fields to a control system instruction are simulated, thus verification of control system software and hardware is realized.

Description

technical field [0001] The invention relates to a dynamic simulation test method, in particular to a joint test method of a dynamic simulation device and an engineering control system. Background technique [0002] The flexible DC technology (VSC-HVDC) based on the voltage source converter can supply power to the island, independently adjust the active and reactive power, will not cause commutation failure, does not require reactive power compensation, and can carry out long-distance submarine cable transmission, etc. advantage. In recent years, the theory and engineering construction of this type of power transmission technology are developing rapidly all over the world. [0003] On the basis of the past, the high-voltage direct current transmission technology (MMC-HVDC) based on the new modular multi-level voltage source converter (MMC) has realized the application in the field of high-voltage direct current transmission technology. This technology has low requirements o...
