Simulation And Modeling Of HVDC Transmission System

Controlling system, which is the core unit of HVDC project, has nice flexibility to exert the best performance of regulating and for various running methods. Simulation of the control system of HVDC is an important way to research how to achieve good transient and stable performance of AC and DC power system network. As electromagnetism transient real-time simulation has played an important role in researching, testing and detecting the DC control and protection system, the paper adopts this method to simulate it based on the self-developed software. The paper builds the primary and secondary system model, and it optimizes the numbers of the nodes so that it can improve the efficiency of computational and achieve the demand of real-time and accuracy of the simulation. Then it simulates the CFC and BPPC control system. Combined with operating parameters commonly used in engineering, the paper validates and analysis the validity of the model, and the results show that this method is effective.
