摘要:
静止无功补偿器(SVC)是电网中应用广泛的并联FACTS装置。在电力系统的运行中,SVC的优化配置对其更好地发挥作用具有很大的影响。针对SVC结合智能算法进行配置,提出一种结合花朵授粉算法寻优的SVC优化配置方法。该方法中需要涉及的参数相对其他算法较少,同时将涉及经济性方面在内的多个因素综合考虑。最终,通过算例仿真说明该方法的正确性及相应效果,对SVC优化配置的研究有实际的参考意义。

摘要:
针对某实际500 kV并网静止无功补偿器(SVC)故障率高、维护代价高等问题,研究SVC的无功电压支撑能力及相关处置措施.首先,分析SVC对稳态无功平衡和电压调节的作用,特别是对电网小负荷运行期间无功电压调节的影响.然后,通过对比分析SVC与STATCOM、常规发电机组的暂态电压支撑能力,评估SVC对电网暂态电压稳定的影响.最后,综合考虑SVC的稳态电压调节作用和暂态电压支撑能力、电网安全稳定运行的需求等因素,提出该SVC的处置措施建议.

摘要:
以我国实际电网为例,研究大型风电场对送端电网暂态稳定特性的影响规律.研究表明,由于风电机组本身不存在功角同步的问题,在送电通道功率不变的情况下,风电接入后系统的暂态功角稳定性有所改善,但导致系统的暂态电压稳定性变差.静止无功补偿器(static var compensator,SVC)有利于提高送端电网的暂态功角稳定性和暂态电压稳定性.

摘要:
针对风电并网的低电压穿越(LVRT)问题,提出采用静止无功补偿器(SVC)和模糊变桨距联合控制的方法进行改善.在电网电压骤降时,通过加入模糊控制的变桨距控制策略提高系统低电压穿越能力,同时利用SVC进行无功补偿,即使风力发电系统出现故障,并入电网的网点处电压也不会大幅度下降,电网可以保持暂态稳定,发电系统低电压穿越能力得到提升.最后在Matlab/Simulink中建立发电系统和静止无功补偿器并网仿真模型.结果 表明:二者联合控制在电网电压骤降时,能够将电压维持在要求的范围内,有效地提升了系统稳定性,保证机组能在规定时间内不脱网运行.

摘要:
The stability of the isolated grid with high penetration of renewable energy sources is becoming more and more serious. This paper studies the control strategy of stabilizing the fluctuation of renewable energy by high energy consumption load based on an actual industrial power system in the east of Mongolia. The model of a coupling relationship between active power consumed by electrolytic aluminum and DC voltage is built. The control strategy of using static var compensator (SVC) to adjust the voltage to change the active power of the aluminum load is proposed based on the voltage regulation principle of SVC. The primary frequency modulation of the thermal power unit is fully considered in the control strategy. The adjustment ability of the load is deeply excavated so that the fluctuation of wind power can be offset effectively. A calculation method of compensation capacity of SVC is proposed, which can provide capacity reference of SVC for the actual site installation. The simulation model is built on the RTDS,and the power system can maintain stability in the case of high or low permeability and extreme fluctuation of wind power, which verifies the effectiveness of the proposed control strategy.%高渗透率的可再生能源接入使得孤立电网的稳定性问题日益突出.文章以蒙东某实际工业电力系统为例开展了高耗能负荷平抑可再生能源发电波动的控制策略研究.首先,建立了电解铝负荷消耗功率与直流电压的耦合关系模型.其次,基于静止无功补偿器(static var compensator,SVC)的调压原理,提出了利用SVC电压调整实现电解铝负荷调节的控制策略.所提控制策略在考虑火电机组一次调频的基础上,深度挖掘了负荷调节能力,有效平抑孤立电网中风电的有功波动.同时提出了一种SVC补偿容量的计算方法,为实际现场装设SVC提供容量参考.最后在RTDS (real time digital simulator)上搭建仿真模型,在风电高、低渗透率以及风电极端波动的情况下系统都能维持稳定,验证了所提出的控制策略的有效性.

摘要:
本文对静止无功补偿器(SVC)中晶闸管控制电抗器(TCR)与晶闸管投切电容器(TSC)的接线方式进行分析,主要对比了6脉波接线与12脉波接线TCR的区别以及TSC三角形角内接线与角外接线方式下晶闸管与电容器的电压与电流定额.在无功补偿等值电纳的计算中,为了避免瞬时无功功率理论中的Clark变换,采用FBD(fryze-buchholz-dpenbrock)法提高计算速度,并搭建Matlab/Simulink模型进行仿真,验证其正确性.%In this paper,the wiring method of the thyristor controlled reactor (TCR) and the thyristor switched capacitor (TSC) in the static var compensator (SVC) is analyzed. The difference between 6-pulse and 12-pulse TCR wiring is mainly compared and the voltage and current of the thyristor and the capacitor at inner wiring and outer wiring of TSC triangle is also compared. In the calculation of equivalent susceptance of reactive power compensation,the FBD method is adopted to avoid Clark transform in the instantaneous reactive power theory and to improve calculation speed. The Matlab/Simulink model is set up for simulation and correctness verification.
