摘要
运行在SVC模式下的可控整流器型直流融冰兼SVC装置,其整流阀触发角的调节范围(控制域)通常在90°附近的较小区间内,但缺乏明确的分析。结合装置运行时的基本约束条件,从考虑换相角的前提下各量与触发角间的关系出发,分析了其在无功补偿运行模式下的控制域和无功补偿量解析表达式,并对分析结果的正确性进行仿真验证。研究结果对可控整流器型直流融冰兼SVC装置参数分析及控制参数优化设计具有参考价值。
The trigger angle α is in a narrow area near 90° when controlled rectifier type SVC/DC-deicers are being operated on SVC mode,but analysis on the control domain is deficient and undefined.The control domain is confirmed and the VAR character function in the control domain is proposed by function derivations.These derivations,including the relationships between I,Ud,Id and α,are based on its operation constraints.The control domain is defined and analyzed.Simulation demonstrates the proposed control domain analysis is feasibility and effectiveness.These results can be used in parameters analysis or controller’s parameters optimizations of controlled rectifier type SVC/DC-deicers.
