利用迭代法分配电厂各机组负荷量

Using Iterative Method to Allocate Load between Units in Power Plant

在供热情况下,机组煤耗特性曲线偏离设计值,原厂级AGC系统无法合理分配电厂各机组负荷量。文章在等耗量微增率理论基础上,采用迭代法,提出一种新的厂级AGC分配方案。试验结果表明,对比原方案节能效果明显,总发电标准煤耗率明显下降,是一种实用的节能负荷分配算法。

Under the condition of heat supply, the coal consumption characteristic curve of the unit deviates from the design value, and the original AGC system cannot distribute the load between units in power plant. Based on the theory of equal consumption and slight increase rate, the article adopts iterative method and proposes a new AGC distribution scheme at the factory level. The test results show that compared with the original program, the energy-saving effect is obvious, and the coal consumption rate of the total generation standard is obviously reduced. The proposed algorithm is a practical energy-saving load distribution algorithm.
