Abstract

Abstract: Based on SG-OSS DTS(Smart Grid Operation Support System-Dispatcher Training Simulator), the overall design of VSC-HVDC (Voltage Source Converter) simulation is presented. Steady-state simulation model of multi-terminal VSC-HVDC and hybrid solution algorithm of AC/DC system are discussed, and an alternating solution algorithm based on Newton-Raphson method is proposed. Finally, simulation results prove validity and effectiveness of proposed model and algorithm. The method has been applied to electric power dispatching and control center of Fujian Province. Application results show that dispatcher training system with VSC-HVDC can build a high fidelity training simulation platform for electric power dispatch and operation. It meets training, exercise and evaluation needs of electric power dispatching and control center.

Key words: VSC-HVDC, steady-state simulation model, alternating solution algorithm, DTS, training simulation
