Simulation Study of Energy Saving and Loss Reduction for Thermal Power Plants with Power Plant Section

To address the issue of energy waste in some parts of the plant power system in the power plant, this paper proposes to use the comprehensive energy-saving measures of zero lossing current limiting breaker equipment(ZLB), Variable-frequency Drive(VFD) and transformer cold standby for loss reduction. First, the working principles of ZLB limiting short-circuit current, delicate control of VFD and cold standby of transformer are elaborated; then, the corresponding loss calculations are carried out in combination with the energy-saving measures of ZLB, VFD and transformer cold standby to assess the effect of the proposed measures in reducing the plant power consumption rate; finally, the energy-saving effect is verified in MATLAB, and the results show that the equipment used in this paper and its optimized The results show that the equipment used in this paper and its optimization measures can significantly reduce the plant power consumption rate, reduce energy loss, improve the economic efficiency of the power plant, and have certain application value in energy saving and consumption reduction in power plants.
