中文摘要江苏电网具有电源分布不均、负荷增长迅速、无功储备不足等问题,是典型的易发生电压稳定问题的系统。在仿真中考虑了动态负荷模型和参数的影响,分析了2006年江苏电网负荷增长和负荷中心大扰动后的电压稳定性,并与采用原有数据的计算结果进行了比较。结果表明,现在一些电网电压稳定分析常沿用以往角度稳定分析所用的静态负荷数据的作法存在较大的不足,不能完全满足电压稳定分析和制定应对措施的要求。还就采用静止无功补偿器(SVC)提供动态无功支持,提高江苏系统电压稳定性进行了研究。结果表明,现阶段采用SVC提供江苏电网扰动时负荷的动态无功支持,提高电压稳定性是一项可行的措施。; Jiangsu power grid is the typical system to easily occur voltage instability for the unbalance of electrical source's disposal,the rapid load's increase,lacking of reactive power storage,etc.Considering the influence of dynamic load models and parameters in simulation,the voltage stability of 2006 Jiangsu power system after the increase of load demand and the big disturbance in load center was analyzed and compared with the result based on the original data.The result shows that there is a big shortage in the way of following static load models and parameters used by the former angle stability analysis,which doesn't adapt to the requirement of voltage stability analysis and making measures.What's more,the enhancement of voltage stability of Jiangsu system,through static var compensator(SVC)providing dynamic reactive power support,was studied.The result indicates that it is really feasible to adopt SVC to supply load dynamic reactive power to Jiangsu power grid for increasing voltage stability.
