| 摘 要： | 本文提出了一种预测超高压变电所空间电场分布的方法。首先用模拟电荷法得出了能确定场强最大值的通用曲线,然后对最感兴趣的场强区的数值计算方法进行了分析,所得的结果与测量值进行了比较,最后提出一种对整个变电所的场强统计分布规律进行估算的方法:“所划为块——分块计数——查图修正——合成全所”,其结果已能满足工程上初步设计的要求。且为制订国家标准“超高压输电线路及变电所的静电感应”等提供了依据。

| Abstract: | The method for predicting the space field distribution in UHV AC substations was introduced.First, the generalized curves of maximum electric field strength were calculated with charge simulationmethod. Then the numerical method for calculating the most interested region within the substationswas analysed. The results were very closed to the measured data. At last, the simplified method for e-valuating the statistical regularities of the electric field distribution in the designed substation was rec-ommended. The method will satisfy the requirements of the engineering design at its initial stage. It ishelpful for enacting our national criteria of the electrostatic induction under UHV transmission linesand in the UHV AC substations. |
