【摘要】：虛擬同步發(fā)電機(jī)(virtual synchronous generator,VSG)可模擬同步發(fā)電機(jī)運(yùn)行機(jī)制,并為系統(tǒng)提供慣性和阻尼支撐.在孤島模式下,VSG并聯(lián)運(yùn)行多采用分散下垂控制,不具備頻率恢復(fù)以及有功出力合理分配等功能,為此,本文提出了一種基于一致性的并聯(lián)VSG分布式控制方法,可改善系統(tǒng)頻率與有功功率特性.本文首先介紹了傳統(tǒng)VSG控制的數(shù)學(xué)模型,并在此基礎(chǔ)上設(shè)計(jì)了VSG并聯(lián)系統(tǒng)頻率恢復(fù)及有功出力合理分配的整體方案.在分布式控制模式下,相鄰VSG只需少量信息交互即可控制頻率恢復(fù)到額定值,并可實(shí)現(xiàn)功率的按需分配,滿足了不同用戶的定制需求.仿真結(jié)果驗(yàn)證了所提方法的正確性和有效性.
[Abstract]:Virtual synchronous generator can simulate the operation mechanism of synchronous generator and provide inertia and damping support for the system. In the isolated island mode, the distributed droop control is used in parallel operation of VSG, which does not have the functions of frequency recovery and rational distribution of active power. Therefore, a distributed control method of parallel VSG based on consistency is proposed in this paper. The system frequency and active power characteristics can be improved. This paper first introduces the mathematical model of traditional VSG control, and then designs the overall scheme of frequency recovery and rational distribution of active power in VSG parallel system. In the distributed control mode, the control frequency of adjacent VSG can be restored to the rated value with only a small amount of information exchange, and the power can be allocated according to demand, which can meet the customization needs of different users. Simulation results show that the proposed method is correct and effective.
