Abstract
The invention relates to a high-reliability reactive power compensator. A voltage transformer and a current transformer are arranged at a power supply line end; voltage of the alternating current is inputted to a signal processing and acquisition module via the voltage transformer; the current is inputted to the signal processing and acquisition module via the current transformer; amplitude reduction and acquisition are carried out on signals in the signal processing and acquisition module and then the signals are inputted to an A /D conversion module for digital to analog conversion; the converted signals are inputted to a single chip microcomputer; and the control end of the single chip microcomputer is connected with a relay via an isolating and driving circuit. According to the high-reliability reactive power compensator, stable and reliable operation can be realized at a low cost, control parameters can be flexibly configured, accurate power factor values are obtained, and automatic control and remote wireless control can be realized.
Description
Technical field
The present invention relates to supply line's condition monitoring field, particularly a kind of highly reliable reactive power compensator.
Background technology
In remote electric power system, on load end and conveying circuit, certainly lead to certain reactive power consumption, cause larger waste, carry out reactive power compensation so necessary.Mostly existing mode is to add idle unit at the terminal power distribution cabinet of long-range conveying or transformer station, but the data majority that current idle unit gathers is inaccurate, and adopts conditional electronic circuit, and antijamming capability is very poor, and reliability is lower, is difficult to reach desired value.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of highly reliable reactive power compensator, there is feature easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
A kind of highly reliable reactive power compensator, in supply lines terminal, voltage transformer summation current transformer is set, the voltage of alternating current inputs to signal by voltage transformer and processes and acquisition module, electric current inputs to signal by current transformer and processes and acquisition module, in information processing and acquisition module settling signal give blessings and gather after input to A/D conversion module and carry out digital-to-analogue conversion, signal after conversion inputs to single-chip microcomputer, and the control end of single-chip microcomputer is succeeded electrical equipment by isolation and drive circuit.
Described single-chip microcomputer is connected to reset circuit.
In described isolation and drive circuit, isolation method is photoelectricity isolation.
The power end of compensator is connected to Transient Voltage Suppressor.
Described single-chip microcomputer is connected to wireless communication module.
Compared with prior art, the present invention has realized stable and reliable operation with lower cost, and can flexible configuration control parameter, obtains accurate power factor value, and realizes and automatically controlling and remote wireless control.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is carried out to more detailed explanation.
As shown in the figure, the present invention is a kind of highly reliable reactive power compensator, it is characterized in that, in supply lines terminal, voltage transformer summation current transformer is set, the voltage of alternating current inputs to signal by voltage transformer and processes and acquisition module, electric current inputs to signal by current transformer and processes and acquisition module, in information processing and acquisition module settling signal give blessings and gather after input to A/D conversion module and carry out digital-to-analogue conversion, signal after conversion inputs to single-chip microcomputer, and the control end of single-chip microcomputer is succeeded electrical equipment by isolation and drive circuit.
Single-chip microcomputer receives the signal after A/D conversion, calculates power factor, thereby realized the collection to voltage, electric current and power factor in circuit according in house software.Then the value range based on default, according to current collection value, output control signal is by the switching operation of relay control circuit.Single-chip microcomputer is connected to reset circuit, if system is made mistakes, can carry out reset operation.Single-chip microcomputer is connected to wireless communication module, the signal long distance wireless of collection can be sent to host computer for analyzing reference.
The power end of compensator of the present invention can connect a Transient Voltage Suppressor, thus transient suppression disturbing pulse.
