摘要
结合在定联络线功率和频率偏差控制方式下的功率调整情况以及采用的A系列评价标准,分析了河北南部电网在AGC应用方面存在电厂投入AGC积极性不高、火电机组本身的调节特性、供热机组冬季调节容量变小和风电场对电网影响方面的问题。通过实际工作提出了应对措施:一是制定AGC机组运行标准和考核管理办法,定期对机组性能进行测试;二是按参与AGC调节、给定负荷曲线、不参与AGC调节等分配机组控制方式,充分发挥抽水蓄能电站的调节作用;三是在超短期负荷预测的基础上,综合考虑各种约束条件和经济指标,实现最优发电控制。
The situation of AGC（Automatic Generation Control） application in Hebei southern power network,which adopts the active power regulation under TBC（Tie-line and frequency Bias Control） mode with the evaluation standard A,is analyzed,such as low enthusiasm of power plants,poor regulation performance of generating unit,less regulation capacity in winter and influence of wind farms on power network.Countermeasures are proposed：set the operational standards and assessment management rules of AGC units and carry out the unit performance tests regularly;assign different unit control modes（AGC,given load curve and non-AGC） and fully apply the adjustment function of pumped storage plant;consider comprehensively various constraints and economic indicators based on ultra-short term load forecast to achieve optimal generation control.
