| 摘要 | To solve forced power oscillations arising from a thermal power unit's load fluctuation frequently, load control mechanisms and solutions were studied in combining with these actual accidents data. This paper comprehensively analyzes the load control principle and provides a basic accident handling procedure according to the unit's actual condition. According to analysis, inspection and dynamic test results, load fluctuation causes locked-in-place jamming of servo valve. An actuator model is established to simulate the unit's operation under different control parameters. The simulation results show that setting unreasonable control parameters intensifies load fluctuations into forced load oscillation, which is verified by dynamic testing of the unit and the effect of control optimization on operation. This analysis and the resolution of this issue are effective and accurate, providing a valuable reference in the event of a similar accident. It is determined that strict process control of overhaul and in operation can reduce the probability of load fluctuation, and control parameter optimization can avoid forced load oscillation. |
