并联逆变器无互连线控制技术的研究
|
摘要
近年来随着用电设备对电源的容量,性能以及可靠性要求越来越高,使并联逆变器得到了广泛的应用和发展;而无互连线的并联逆变器与有互连线的并联逆变器相比又具低有干扰、高冗余度、高可靠性等优点,因而无互连线的并联逆变器成为当今电力电子学科研究的一个热点。
本文首先探讨了单相逆变器电压电流双环控制器参数的设计方法,接着分析了并联逆变器的环流特性以及传统无互连线并联技术存在的局限性,最后针对于传统的频率和压电的下垂特性控制方法所存在的弊端采用了一种新型调节控制策略,消除了调压和调频程过中引起的调节正反馈,使逆变器均分负载电流,从而有效地抑制了并联环流,避免了正反馈引起的系统振荡。
通过MATLAB/Simulink对无互连线的并联方案进行了仿真,结果表明,它能较好地解决负载的均流问题,有效地抑制环流,但尚需实验的进一步验证。
In recent years, as the requirement of high capacity, quality as well as reliability powersupply increasing, parallel inverters are widely used. Generally, there are two kinds of parallelinverterpower supply systems: parallelinvertersystem with control interconnections andparallelinvertersystem without control interconnections. As the latter has low disturbance,convenience to expand and high reliability, it is studied more and more nowadays.
In this thesis, an inverter controller composed of voltageloopand currentloopwasintroduced, and then we analyzed circulation characteristic of parallel inverters as well as thelimitation of traditional droop characteristic, finally we present a new droop characteristic. Thenew method eliminated the positive feedback which caused by the voltage modulation andfrequency modulation, The new method can divide the load current equally on each inverter, sothis method effectively has suppressed the parallel circulation and has avoided the systemvibration which the regeneration caused.
The MATLAB/Simulink simulation on the new project shows that it can reduce the errorgreatly. But it needs further experiments to confirm.
