Intelligent control system for electromagnetic precise control type electricity-saving device

Abstract

The invention provides an intelligent control system for an electromagnetic precise control type electricity-saving device. An air switch, three current sensors and a pulse width controller are installed on the upper part of a computer case of the electromagnetic precise control type electricity-saving device; a central processing unit (CPU), three current amplifiers, a current comparison amplifier, a current digital amplifier, a timer, a temperature controller, a power amplifier and a low-voltage power supply and a sinusoidal wave former are installed on the middle part of the computer case; the three parallelly-connected current sensors are connected with the CPU through the three parallelly-connected current amplifiers and then through the current comparison amplifier; the three parallelly-connected current sensors are connected with the CPU through the three parallelly-connected current amplifiers and then through the current digital amplifier; and an intelligent control system for the energy-saving control loop can be formed. The system provided by the invention utilizes the magnetic force and the pulse width to continuously precise regulate and control the output power mode of the power supply, so that the power-supply power of the power source and the actually consumed power of the load can be matched precisely and the loaded power supply of the load can be realized; the system also can automatically clear away the harmonic waves and surges in a power supply system so as to provide a high-quality power supply for power equipment; the system also can carry out multiple compensation on the line, improve the power factor, reduce the line loss, increase the line capacity, improve the power efficiency of the system and can obtain double significant beneficial effects of saving electric energy and abating harmonic wave pollution in a power supply network.

Description

technical field [0001] The invention belongs to the technical field of energy saving in the operation of power equipment and electrical equipment in a power system, and specifically provides an intelligent control system of an electromagnetic precise control power saving device, which is used for electric motors, water pumps, fans, electrical lighting systems and electrical equipment. Power saving control. Background technique [0002] In the current development process of my country's modernization construction, the development of electric power has become one of the decisive factors of social and economic development. In my country's GDF, in the process of growth, the high energy consumption per unit of GDP has affected the rapid development of my country's economy, so developing electricity and saving electricity will become the basic policy of my country's long-term development in the future. [0003] At present, there is a lot of energy waste from power grid transmissi...

Problems solved by technology

Second, within the scope of regional power supply, that is, among the terminal user groups, due to different operating conditions, usually only 70-80% of users carry 100% of the power supply, resulting in a further surplus of power distribution capacity

Third, for the motor of a specific unit, in order to ensure the normal operation of the equipment during the peak power consumption, the output voltage of the transformer is often required to be higher than the rated voltage of the motor, and the insufficient number of operating units of most units leads to the rated capacity of the unit. further excess of

But so far, this series of power-saving technologies is not applicable to the power-saving requirements of many operating states of the motor, such as when the motor is working under heavy load, full load and overload conditions (the load is 80-90%, 90- 100%, 10135%), when the power factor of the motor is high (0.65-0.98), when the constant load and constant torque motor is working under heavy load, full load and overload, etc.
