Abstract

The invention belongs to the technical field of computer simulation, and discloses a real-time dynamic simulation test system for a fast frequency response controller of a new energy station. The system is established based on an RT-LAB real-time simulation analysis platform and comprises a new energy station fast frequency response controller hardware circuit and a dynamic system mathematical model, and the dynamic system mathematical model comprises a new energy station model and a power grid model which are established in MATLAB/Simulink; the new energy station fast frequency response controller is interconnected with the dynamic system mathematical model through the I/O physical interface and the MODBUS communication module, so that a frequency step disturbance test, anti-disturbance performance verification and an automatic power generation control coordination test real-time dynamic simulation test of the new energy station fast frequency response controller are realized. The simulation test system provided by the embodiment of the invention is accurate and reliable, can test and verify the performance of the new energy network-related device, provides test data for optimizing the operation strategy of the network-related device, and is beneficial to improving the network-related performance of a new energy station.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a real-time dynamic simulation test system for a fast frequency response controller of a new energy station, and also relates to a real-time dynamic simulation test method for a fast frequency response controller of a new energy station. Background technique [0002] In response to various problems such as the shortage of fossil energy and the environmental pollution it brings, renewable energy power generation represented by wind power and photovoltaics has attracted widespread attention because of its low-carbon environmental protection, mature technology, and large-scale production. In recent years, the proportion of China's new energy installed capacity has continued to show explosive growth. However, due to the large-scale use of power electronic conversion devices connected to the large power grid for new energy and the replacement of conventional power sources in large ...
