Power Generation Performance

Providing peaking auxiliary for wind power will affect the thermal power generation efficiency and reduce generation economic benefit. To realize the coordinated scheduling optimization of thermal power and wind power, the key problem is the economic compensation of thermal power peaking. In this paper, through the analysis of the influence of wind power on thermal power generation performance and thermal power peak load regulation on abandon wind, an economic compensation model based on objective optimization is established. The example analysis shows that cooperation of thermal power and wind power can improve the wind power accommodation level and unit efficiency, and the economic compensation mechanism can guarantee thermal power unit economic benefit effectively.

Through the summary of typical accident, the problem between the over speed protection device of thermal power unit steam turbine and over frequency generator tripping measure is analyzed in island operation of sending ends of regional grid. The optimizing allocation principle between over frequency generator tripping measure and over speed protection equipment is put forward. By a variety of program analysis and comparison, the optimizing scheme is given. Finally, the typical models of thermal power unit steam turbine over speed protection are established in software. Based on a practical power system as an example, the whole process of islanding is simulated. Checking the coordination with existing over frequency generator tripping measure and the relay setting related to power network in the islanding operation, the validity and practicability of the optimal scheme and principle are analyzed. With the method, the regional grid will remain safe and stable.
