[Abstract]:With the increasing of the unit capacity, the AGC control process considering the dynamic characteristics of the unit has no experimental platform suitable for research in the laboratory. New energy especially large-scale wind power grid brings complex power system stability problems. However there is no suitable power system simulation tool to study the power stabilization process of large-scale wind power grid. Therefore, based on the RTDS platform, the design method of the joint simulation control system based on the source network is proposed, and the interface technology of the system is studied in detail. The system consists of three modules: power simulation module, power network simulation module and dispatching system simulation module. This paper introduces the function of each module, the key interface technology between each module and the implementation method. The power supply interface module realizes the data interaction with the RTDS power network module through the RTDS fiber communication interface card GTFPGA. The interface control module of thermal power and hydropower simulator is connected to the power network simulation module through the interface control module built in RTDS. The interface control module receives the mechanical power reference value from the detailed simulator to adjust the actual output of the generator. The power and frequency regulation control module built on RTDS is used to control the actual output of the generator by receiving the dispatching instruction. Wind farm detailed simulation machine is connected to RTDS power network simulation module through wind farm custom interface module. Wind farm custom interface module is a system model based on RTDS/CBuilder platform. The actual output of wind farm can be adjusted by receiving the power instruction of the detailed simulator of wind farm. RTDS power network simulation module can configure the mapping file by Ethernet communication interface GTNET-DNP and serial device module. Realize the data interaction with the simulation module of the scheduling system. The power simulation module uses RTDS as the intermediary to realize the data interaction between the power supply simulation module and the scheduling system simulation module. In this paper, the realization method of the joint simulation control system of the source network is put forward, and the interface technology between the three modules of the system is solved. The actual data of the Mengxi power grid is used to prove the power supply and the power network. The correctness and feasibility of the interface method between dispatching systems. The operation of wind farm in real power network is simulated, and the whole function of the combined simulation control system of source network is verified.
