【摘要】：利用直流進(jìn)行緊急功率支援對(duì)單直流系統(tǒng)有一定控制效果,但其缺乏考慮后續(xù)阻尼以及電壓波動(dòng)等因素。尤其對(duì)于多饋入直流輸電系統(tǒng),該方法則因缺乏協(xié)調(diào)控制而有一定局限性。為此,提出一種考慮上述因素的多目標(biāo)緊急協(xié)調(diào)控制新方法,基于多代理系統(tǒng)(multi-agent system,MAS)技術(shù)設(shè)計(jì)了緊急直流功率支援的控制系統(tǒng),并詳細(xì)分析了3個(gè)主要Agent控制的實(shí)現(xiàn)方式。在緊急控制Agent中定義了緊急功率支援指標(biāo),以量化直流系統(tǒng)緊急提升最小量;在附加信號(hào)調(diào)節(jié)Agent中通過(guò)挖掘最佳控制敏感點(diǎn)進(jìn)行直流附加控制;在逆變站無(wú)功調(diào)節(jié)Agent中定義了電壓敏感點(diǎn)指標(biāo),以篩選多直流中電壓最為敏感的直流逆變站進(jìn)行無(wú)功調(diào)節(jié)。最后在考慮通信延遲的條件下以某多直流饋入系統(tǒng)為對(duì)象進(jìn)行仿真,結(jié)果證明了所提協(xié)調(diào)控制方法的有效性。
[Abstract]:Emergency power support by DC has some control effect on single DC system, but it lacks of subsequent damping and voltage fluctuation. Especially for multi-feed HVDC systems, this method has some limitations due to the lack of coordinated control. Therefore, a new multi-objective emergency coordinated control method considering the above factors is proposed. The emergency DC power support control system is designed based on the multi-agent system (multi-agent) technology, and the implementation of three main Agent controls is analyzed in detail. The emergency power support index is defined in the emergency control Agent to quantify the minimum amount of emergency lifting in DC system, and the DC additional control is carried out by mining the optimal control sensitive points in the additional signal adjusting Agent. The index of voltage sensitive point is defined in the reactive power regulation (Agent) of inverter station to select the most sensitive DC inverter station in order to adjust reactive power. Finally, a multi-DC feed-in system is simulated under the condition of considering the communication delay. The results show that the proposed coordinated control method is effective.
