基于广义最小方差的火电机组控制回路性能评估

Performance Assessment of Thermal Power Unit Control Loop Based on the Generalised Minimum Variance

采用广义最小方差对火电机组控制回路进行性能评估,并使用潜能指标和相对潜能指数来监控回路整定后的性能变化情况。仿真结果表明,使用广义最小方差能很好地对火电机组控制系统进行性能评估。

In this paper,the generalized minimum variance is used for performance assessment of a thermal power unit control loop. The potential index and relative potential index are used to monitor the change of the closed-loop potential after tuning. The simulation results show that the generalized minimum variance can assess the performance of the thermal power unit control system well.
