安徽电网实时发电控制系统设计及实现

DESIGN AND IMPLEMENTATION OF REAL-TIME GENERATION CONTROL SYSTEM FOR ANHUI POWER SYSTEM

为了减轻自动发电控制 (AGC)机组调节负担 ,提高AGC控制合格率 ,提高电网调度自动化水平 ,安徽电网实时发电控制系统利用超短期负荷预计的结果 ,自动调整机组发电计划 ,并自动下发到电厂 ,使发电机组能较为准确地响应系统负荷变化。该系统改变了传统调度人员用电话调度发电出力的方式 ,使发电调度较为科学合理 ,在减轻 AGC机组调节负担和提高电网 AGC控制合格率的同时 ,减轻了运行人员负担、提高了电网运行安全性。一年多的运行情况表明 ,该系统投入小 ,见效明显 ,对以火电机组为主的电网 AGC实用化工作和提高电网调度自动化水平及质量控制有借鉴作用 。

For reducing the manual burden of AGC adjustment, increasing the acceptability of AGC control and improving the level of power system control automation, the presented Anhui real\|time generation control system automatically modifies the generation scheme of the generation sets according to the accurate super short time load forecasting, and sends the modified generation scheme to power plants to make the generation sets respond the change of the load more accurately. By means of this generation control system the traditional dispatching mode of sending down the dispatching order by telephone is changed into a new one and makes the dispatching more rational. This new mode not only can reduce the work of AGC control by operators, but also improve the accuracy of AGC control and the security of power system.
