Research on multi-objective load monitoring for power conservation and environmental protection of coal-fired units

The multi-objective load monitoring method for power conservation and environmental protection of coal-fired units is studied to accurately monitor the power load and reasonably control the load dispatching.Using voltage and current transformers to receive real-time voltage and current signals of coal-fired units.The effective load signal in the signal is collected by the power load measurement and acquisition unit.Based on the effective load signal,the microprocessor establishes a multi-objective load dispatching model for power energy conservation and environmental protection with the minimum coal consumption and pollutant emission as the objective function and the constraints of rotating reserve and unit output as constraints.The model is solved by multi-objective hybrid evolutionary particle swarm optimization algorithm to obtain the best load scheduling scheme and realize load control.The IEEE 1394 protocol is used to realize the load signal transmission during the whole monitoring.Experiments show that this method can accurately monitor power load when noise and different load raising rates are introduced.After using this method to dispatch the load,the coal consumption and pollutant emission can be effectively reduced,and the power energy conservation and environmental protection can be realized.
