Control Methods of Railway Static Power Regulator for V/V Electrified Traction Railway
摘要
Abstract
Considering power quality problems such as negative sequence and harmonic current in electrified railway, railway static power conditioner (RPC) was discussed to carry out the comprehensive compensation in this paper. In order to improve the control effect of RPC, a dual-loop control strategy was constructed, which was composed of repetitive prediction based deadbeat control for current loop and composite sub-PI control for DC-side voltage loop. This approach could realize fast, smooth tracking to the reference current and smooth control for voltage. Taking into account the disturbance and volatility of the system parameters, a recursive least square algorithm based on forgetting factor was adopted to dynamically identify system parameters and enhance adaptability of RPC. At last, the simulation and experimental results have confirmed the correctness of the proposed method.关键词
