Problems solved by technology

[0006] The power supply department also adopts power rationing to control power consumption, but this obviously has a negative impact on people's lives and industrial production
In order to maintain production and life, some enterprises and residents use various generators or UPS for emergency use. This method can only solve the problem of emergency power supply, and cannot use valley power to reduce the burden of peak power.

Abstract

The invention discloses an intelligent peak-shaving energy-saving power supply which comprises an intelligent modulation controller, a DSP (Digital Signal Processor) controller, an isolation transformator T, a bidirectional inverter NB and an electrical energy memory unit, wherein, the intelligent modulation controller is connected with a commercial power circuit and used for detecting the voltage of the commercial power circuit and then sending the control signals to the DSP controller; the DSP controller is connected with the intelligent modulation controller and the bidirectional inverter NB, receives the control signals sent by the intelligent modulation controller, and controls the working state of the bidirectional inverter NB according to the control signals; and the bidirectional inverter NB is connected with the electrical energy memory unit and is also connected with the commercial power circuit through the isolation transformator T. The intelligent peak-shaving energy-saving power supply can adjust power network peak-valley balance and improves the stability of an electric power system.

Description

technical field [0001] The invention relates to an intelligent energy-saving peak regulation power supply. Background technique [0002] During the power supply process of the grid system, there are peaks and valleys of grid load. The electricity load is a constantly changing quantity. For a region, the characteristics of the load change mainly depend on factors such as the structure of the electricity industry, the region, seasonal changes, economic development, and living standards. The unevenness of electricity load in time makes more electricity consumption in a certain period of time, and less electricity consumption in a certain period of time, which forms the peak load and valley load of electricity consumption. The greater the peak-to-valley difference, the less economical the operation of the power grid. From the typical daily load curves of power grid in winter and summer in a certain area, it can be seen that the daily load of electricity consumption generally h...
