摘要
目前火电厂单机负荷控制方式难以实现厂内机组间负荷的优化分配和调度,本文利用厂级AGC开展基于等微增率算法的厂级负荷优化分配技术研究。优化后的AGC系统既能满足电网安全经济运行的需要,又能提高发电厂节能与协调运行水平,还可以减小电厂机组异常对电网造成的冲击,有利于提高机组的安全稳定性能。并以实际算例说明,与其他负荷分配方式相比,利用基于等微增率算法的厂级负荷优化分配策略时发电厂的总煤耗量最低、经济性最好。
The current stand-alone load control mode in power plant was difficult to achieve optimized the load allocation and scheduling among different units in power plants.This paper carried out research of optimal load distribution technology by using the plant AGC, based on incremental method. Optimized AGC system was able to meet the needs of safe and economic operation of＂ power grid, also could improve the power plant energy saving and operation level, reduce the abnormal impact to the power grid caused by power plant, and was conducive to improve the security and stability of unit performance. Practical examples showed that compared with other distribute methods, the total coal consumption of plant was smallest, and the economic was the best after the use of the load optimal distribution system of power plant.
