Taking the nozzle , parallel capacitor and shading cover into consideration in the calculation . based on it , for solving disadvantage of contrived interfe re of the conventional charge simulation method , it ' s the first time to propose the optimization charge simulation method in this thesis , and numerical computation for the demonstrated example have been achieved to verify the feasibility and validity 并在此基础上,针对传统模拟电荷法在具体应用过程中人为干预的问题,首次将遗传算法引入模拟电荷法的布点设计中,提出了智能优化模拟电荷法的新方法,并对具体实例进行电场数值求解,验证其可行性和有效性。
First the paper use the different four network operating condition as the primary given conditions and set the 330 / 220kv transformer tap changer position in the standard position , adding the paralleled capacitor bank sets one by one into the network to change the amount of the input reactive power , thus obtained four sets of the 330kv and 220kv bus voltage and the active and reactive power losses changing curves 进而研究了在每一确定并联补偿电容器组投入量条件下,随联变调压档位变化而产生出的一组并联补偿量、母线电压与损耗的变化曲线。进而选出了陇南电网在四种选定电网运行方式下、有功损耗最小条件下的最优综合控制组合曲线。
Then the paper uses the same typical four network operating conditions as the primary given conditions and when adding one set of the parallel capacitor bank , changing the 330 / 220kv transformer tap changer position step by step to change the transformer ration , through this study methods this paper found out all the optimized combination of the tap changer position and the amount of input reactive power , also obtained four sets of the 330kv , 220kv and hokv s / s bus voltage and the active and reactive power losses changing curves . through analyzing the optimized combination control curve and the network power flow , the paper generalizes the rules as following : the chief measure of coordinative control is inputting shunt reactor in chengxian s / s in winter time both in the planning year of 2010 & 2005 ; in summer time in planning year of 2010 the chief measure is to input proper shunt capacitor 本研究通过分析所获得的最优综合控制组合曲线及电网潮流,总结出了如下规则:陇南电网在2005年及2010年冬大、以及2005年夏小运行方式下,综合控制应以成县变投入适量并联补偿电抗器作为主要措施;在2010年夏小运行方式下则投入适量并联补偿电容器作为主要措施,再辅助以选择合适的主变有载调压分接头来调节,达到控制网内无功潮流分布合理、各变电站母线电压在理想的范围内时电网有功损耗最小,从而也提高了电网安全运行水平及供电质量。
