地区电力调度EMS应用功能需求及算法

为使地区电力调度EMS满足地区电力网安全经济运行和逐步推进的电力市场的需要，讨论了地区电力调度EMS在常规已共识的功能的基础上迫切需要增加的新功能及实现算法。这些功能包括电能质量在线监测，优化调度（主变压器优化运行，消弧线圈优化运行，无功电压运行质量价，无功电压集中闭环优化控制），提高负荷预测数据源可靠性的措施，谐波电量计算系统的防窃电等。文中所述部分功能已在长春地调EMS中开发成功，收到了良好效果。

DEMANDS AND ALGORITHMS FOR NEW APPLICATIONS OF EMS FOR DISTRICT POWER CONTROL CENTER

Additional functions and algorithms are discussed based on the traditional EMS in a district electric power dispatching center to ensure safe and economical operation as well as to promote the development of the power market. The functions include on-line electric energy quality supervising, optimization dispatching (transformer optimized operation, automatic tap setting of arc-extinguishing coil, reactive voltage operation quality evaluation and its centralized closed-loop optimal control), measures to improve the reliability of load forecast data source and harmonic electric energy telemetering reading and electric theft prevention. Some of these functions have been successfully applied in Changchun sub-transmission power network.
