摘要/Abstract

摘要： 随着直流负荷和电源在电网中应用越来越广泛,交直流混合配电系统是未来低压电网的发展趋势。在综合考虑了功率控制、直流母线电压控制和直流电源及负荷接入的情况下,提出了交直流混合配电系统电压源换流器的分层控制模式和各层的控制策略,建立了各模块的数学模型。基于PSCAD电磁暂态仿真平台建立了交直流混合配电系统的仿真模型,通过各种运行模式和扰动下的仿真研究验证了交直流混合配电系统控制策略的有效性。

Abstract: As DC loads and power supply are more and more applications in the grid, AC/DC power distribution system is the future development trend of the low voltage power grid. The modeling and simulation of AC/DC hybrid power distribution system are studied in this paper. Considering the power control, DC bus voltage control and DC power supply and load access, the hierarchical control model of voltage source converter for AC / DC hybrid distribution system and the control strategy of each layer are proposed, and on this basis, the mathematical model of each module is established. Based on PSCAD electromagnetic transient simulation platform, the simulation model of AC / DC hybrid power distribution system is established, and the effectiveness of control strategies for AC / DC hybrid power distribution systems are validated through the simulation under various operating modes and disturbances.

Key words: AC/DC power distribution system, control strategy, voltage source converter, power control, simulation verification
