摘　　要：电力系统基础数据是电网安全经济运行的重要基础,主要包括量测和状态估计结果两部分,对其准确性进行定量评估十分重要。针对传统的量测与状态估计结果准确度评价方法存在的不足,提出了量测与状态估计结果准确度的改进评价指标,并开发了实用化应用软件。算例部分给出了这些评价指标在南方电网内某电网的实际应用情况。It is very important to quantify the accuracy of power system basic data, which are mainly composed by two parts ： meas- urements and state estimation results, as these data are the crucial security-economy basis of the power system operation. Aiming at the shortage of traditional accuracy evaluation of measurements and state estimation results, this paper proposes improving evaluation indices for them, and develops a practical software. The case study on certain power system in China Southern Power Grid by using the proposed evaluation indices is given in the paper.
