Real-time simulation research of high frequency link DC solid state transform based on RT-LAB
摘要
Abstract
This paper aims at the simulation problem which is caused by multiple modular characteristic and high frequency of high frequency link DC solid state transformer (HFL-DCSST).The method of achieving HFL-DCSST's real-time simulation is presented and the theory is analyzed.In the aforementioned method,the control system is achieved in CPU while the main circuit is completed in FPGA.Not only can this action satisfy the demand for simulation step but also make full use of resource.In order to solve the problem which from HFL-DCSST's multiple modular characteristic and high frequency,the theory of inductor segmentation is analyzed.And then,the HPL-DCSST model can real-time running with multi-FPGA simulator.At last,a model of HFL-DCSST is completed in this way,and the result of comparative experiment with Matlab offiine simulation verifies the correctness of the theory and the practicality of HFL-DCSST's real-time simulation.关键词
