摘要
随着珠澳地区经济快速发展,电网电缆化改造工程与新建输电电缆的增多,电缆运行时提供的容性无功也随之增多。珠澳电网感性无功补偿装置配置不足,珠澳地区春节期间电压偏高问题日益突出,为此,根据珠澳地区春节期间小方式下的电网结构及珠海澳门春节期间负荷预测,对春节期间珠澳地区电压调控方法进行分析,使用BPA进行仿真计算得到调控策略。最后,通过春节前的电压调控策略仿真研究,将厂站电压不超238 kV作为边界条件,确定了在高、中、低三种不同负荷水平下珠澳电网具体调压策略,明确了所需电厂进相机组的具体数量。电压调控策略在2022年春节的成功应用表明了策略的重要性,为春节期间电压调控提供了重要的参考价值。
With the rapid economic development of the Zhuhai-Macao region,as the number of cabling reconstructing and new transmission cables has increases,so the capacitive power provided by the cables during operation also increases.For the lack of reactive power compensation equipment in zhuhai-Macao power grid,the problem of high voltage during the Spring Festival becomes more and more prominent.Therefor,according to the Zhuhai-Macao region power network during the Spring Festival and load forecast during the Spring Festival,the voltage control method during the Spring Festival of Zhuhai-Macao region were analyzed,then the calculated using BPA simulation was used to formulate regulation strategy.Finally,through simulation study of the voltage regulation strategy before the Spring Festival,the specific voltage regulation strategy of Zhuhai-Macao power grid was determined by using simulation which the boundary condition is the voltage of the transformer subtations can not exceeding 238 kV under high,medium and low load levels,meanwhile,the number of phase-lead power units was determined.The successful application of the control strategy of the voltage,which is also providing important reference value of voltage control during the Spring Festival.
