Abstract
The invention belongs to a fuzzy control electricity saving method using a fuzzy control technology. Operation condition of an electromotor is fed back to a fuzzy closed loop controller through a signal transformer, the fuzzy closed loop controller processes fuzzy reasoning to operation condition data received from the electrometer, a voltage regulation coefficient is generated, the voltage regulation coefficient is converted into corresponding delay time through a control loop, and supplied voltage is transformed through a drive circuit. the fuzzy control electricity saving method has the advantages that interior structure is optimized, operation steps of a user is reduced, installation is convenient, energy is conserved, and efficiency is high.
Description
Technical field
The invention belongs to a kind of employing fuzzy control technology, control the power-saving method of motor.
Background technology
Continuing of China's power tense proposes a serious problem to social life.In fact only can't resolve this problem by accelerating power construction.The data demonstration, the present electric power consumption of China is only second to the U.S., occupies the second place of the world, and output value energy consumption is but three times of world average level, becomes one of country that output value energy consumption is the highest in the world.Have the expert to do individual metaphor, the annual power consumption loss that domestic electricity effect lowly causes is equivalent to two pipe of reinforced concrete at Three Gorges Power Stations.So, how to improve energy efficiency, prevent energy waste, the development power-saving technology becomes the road that China implements the Scientific Outlook on Development and should walk.2004 China " energy-conservation medium-term and long-term ad hoc planning " proposition and the sensing of " the environmental protection storm " of State Environmental Protection Administration all be this.So all kinds of factor has all stimulated the expansion of domestic economize on electricity potential market.Specialty research institution points out, the present Chinese second largest market that has become after the U.S., and may replace the buyer that the U.S. becomes economize on electricity market, whole world maximum fully in recent years.At present, there are different energy-saving controller for electric motor products in the U.S., Japan, but price, the maintenance level requires high, should not be in the universal use of China.
Summary of the invention
The present invention is directed to above deficiency, the fuzzy control power-saving method that provides a kind of current collection power technology, electronic technology, intellectual technology, modern control technology to be integrated.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of fuzzy control power-saving method, by the operating condition of signal transmitting device with motor, feed back to the fuzzy closed loop controller, after the fuzzy closed loop controller carries out fuzzy reasoning to the motor operating condition data that receive, produce voltage regulation factor, convert corresponding time of delay to by control loop again, change service voltage by drive circuit, play energy-conservation purpose; The signal transmitting device is feedback speed signal transmitter, temperature feedback signal transmitter, pressure feedback signal transmitter, flow feedback signal transmitter, the signal transmitting device is serially connected between electrical source of power and motor, the Closed Loop Fuzzy Control device adopts independently metal shell, and is connected with the RS485/232 communication interface.
The invention has the beneficial effects as follows:
The fuzzy control power-saving method has been optimized internal structure, has reduced user's operating procedure, and easy for installation, energy-saving benefit is high.
Embodiment
A kind of fuzzy control power-saving method, by the operating condition of signal transmitting device with motor, feed back to the fuzzy closed loop controller, after the fuzzy closed loop controller carries out fuzzy reasoning to the motor operating condition data that receive, produce voltage regulation factor, convert corresponding time of delay to by control loop again, change service voltage by drive circuit, play energy-conservation purpose; The signal transmitting device is feedback speed signal transmitter, temperature feedback signal transmitter, pressure feedback signal transmitter, flow feedback signal transmitter, and the signal transmitting device is serially connected between electrical source of power and motor.
The below lifts an example and is illustrated:
Example: the application in the cement plant, 90KW ball mill are constant speed varying load class, and motor operate power factor only has 0.6, use the power factor of rear motor operation to reach more than 0.95.
