Abstract
A voltage regulation graded compensation device relates to the field of electrical technology. The voltage regulation graded compensation device comprises a microcomputer controller, a main transformer tapping switch, a voltage regulator and a capacitor. The microcomputer controller is connected with a voltage transformer and a current transformer. The main transformer tapping switch and the voltage regulator are connected with the microcomputer controller. The voltage regulator connects the capacitor and a bus. On the premise of ensuring that the voltage of the bus is stable, the voltage at the output end of the capacitor is changed to ensure that the output capacity of the capacitor meets the system requirement. The voltage regulator makes tapping judgment and issues an order according to input current and voltage signals. A main transformer tap of a substation is regulated in order to regulate the voltage and ensure the qualified rate of the bus voltage. The output voltage of the voltage regulator is regulated in order to change the reactive power output of the capacitor. The voltage regulation graded compensation device has corresponding display and signal functions.
Description
Technical field
The present invention relates to technical field of electricity, be specifically related to a kind of pressure regulation step compensator.
Background technology
Energy-saving and emission-reduction have been the topic of the common concern in the whole world, and it directly affects the mankind's life condition, restriction national economic development.At present power department to saving energy and decreasing loss work pay much attention to, start with from voltage power-less management aspect, dropped into a large amount of funds, developed many voltage power-less management devices, quality of voltage is effectively improved.But because current idle regulating measure is backward and the problem such as capacitor overvoltage in service, overcurrent, life-span, make voltage power-less management devices can not bring into play it and should have effect, can not remain voltage and idle desired index, capacitor compensation does not reach due economic technology benefit yet, can not give full play to the potentiality of equipment.
For the backward problem of voltage power-less regulating measure, my company has developed pressure regulation step compensator, it is broken through from regulating measure, do not adopt capacitor switching method, adopt regulating capacitor both end voltage to change output capacity, the problem such as solved the operating overvoltage of capacitor, shove, changing lags behind is adjusted to real-time adjusting.Pressure regulation step compensator can also be transformed into adjustable inductive reactive power compensation device by fixing shunt capacitor.Significantly reduce grid line loss, improve the quality of power supply, improve equipment safety operation level, increase the economic benefit of power supply enterprise, the in the situation that of new power plant construction not, improve power supply capacity, for the situation that solves current domestic power tense is contributed.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pressure regulation step compensator, purport improves voltage power-less managerial skills greatly, significantly reduce loss on lines and tranformers consumption, improve power factor, improve power supply capacity, improve the effect of power system operation reliability, improve the economic benefit for electricity consumption enterprise.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of pressure regulation step compensator, comprise microcomputerized controller, main transformer shunting switch, voltage regulator and capacitor, described microcomputerized controller is connected with voltage transformer summation current transformer, described main transformer shunting switch is connected with microcomputerized controller respectively with voltage regulator, described voltage regulator is by capacitor and bus (6KV, 10KV or 35KV bus) couple together, ensureing under the prerequisite that busbar voltage is stable, change capacitor output end voltage, to ensure that capacitor output capacity meets system requirements, voltage regulator is according to the current and voltage signals of input, carry out tap judgement, give an order, regulate transforming plant main transformer tap to ensure busbar voltage qualification rate to adjust voltage, regulate the output voltage of voltage regulator to change capacitor without work output, and there is corresponding demonstration and semiotic function.
The present invention starts with from regulating measure, do not adopt capacitor switching method, and adopt regulating capacitor terminal voltage to change the output capacity of capacitor, and solve under the changeless prerequisite of capacitor installation, make the problem of reactive power auto-compensation with load variations.Solve under the changeless prerequisite of capacitor installation, made the problem of reactive power auto-compensation with load variations.The fixing access of capacitor is not divided into groups, and its output capacity can regulate continuously.
The invention has the beneficial effects as follows: adopt voltage regulator to change capacitor-end voltage, thereby change idle output capacity, carry out regulating system power factor with this.This device without overvoltage and shoving, can be realized timely adjustment in adjusting, and ensures that capacitor operates in below capacitor rated voltage forever, ensure that capacitor uses safety, increase the service life, the fixing access of capacitor is not divided into groups, and its output capacity can regulate continuously.
