基于时域指标的火电机组负荷控制系统性能模糊综合评价

Fuzzy comprehensive assessment of thermal power unit load control system based on time domain index

传统基于最小方差准则的火电机组负荷控制系统性能评价方法计算量较大,主要评价系统的随机性,而对系统确定性评价较少。对此,本文提出了一种新的基于时域指标的火电机组负荷控制系统性能模糊综合评价方法,利用隶属度函数对总体时域指标划分了性能评价等级,实现对机组负荷控制系统性能的定性评判,并采用火电机组负荷控制系统仿真模型数据验证了该评价方法的有效性和可行性,结果表明该方法计算量小,易于实现,评价结果准确。

This paper established performance evaluation system for coordinated control systems based on time domain index. A new evaluation method,the fuzzy comprehensive evaluation method is proposed. The membership function was used to divide the level of performance evaluation qualitatively. Finally, the effec- tiveness and rationality of the above model was verified by the model simulation data.
