Description
Technical field
The present invention relates to power system reactive power compensation field, the reactive power compensation control system that a kind of double-bus specifically developed for industrial electrical network quality controlling and reactive power compensation controls.
Background technology
Reactive power compensation control system at present designed by each producer, most Problems existing adopts single busbar connection to control, circuit for double-bus needs two controllers jointly to complete, the outside line adopting two controllers to carry out controlling is complicated, the use of two controllers simultaneously causes the wasting of resources, increases cost.
Summary of the invention
The present invention is the weak point for avoiding above-mentioned technology, thus the reactive power compensation control system of a kind of double-bus control of development and Design targetedly.
The technical problem that the present invention solves adopts following technical scheme:
The reactive power compensation system that double-bus controls, is made up of power unit, double-bus, output, reactive power compensation branch road, sampling section, controller and display section;
Described double-bus is: I section bus, II section bus;
Described reactive power compensation branch road comprises: two vacuum contactors, electric capacitor, discharge coil, discharge indicating lamp, lightning arrester, reactors, and wherein said vacuum contactor is the contactor connecting described reactive power compensation branch road and described double-bus;
Wherein, described controller is connected with described sampling section, described display section and described vacuum contactor respectively;
Described two vacuum contactor states interlocking.
Described power unit adopts the Width funtion power module of 85-265VAC/DC;
Described output adopts plug binding post to be connected with secondary circuit;
Described sampling section adopts two-way voltage sample and four road current samples;
Described display section adopts carrying Chinese word library screen and having man-machine dialog interface of 320*240.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, present invention employs double-bus to control, a controller controls the switching of reactive power compensation branch road on two sections of buses, resource is fully used, avoids unnecessary waste.
2, two vacuum contactors on same reactive power compensation branch road are set to state interlocking by the present invention, namely when a certain road reactive power compensation branch road drops into, another section of bus can not call this road reactive power compensation branch road again, can adopt after Input Mode removed by this branch road, and the switching avoiding branch road is chaotic.And when two sections of buses all need reactive power compensation, in reality, only a residue branch road does not drop into (all the other branch roads come into operation all), the branch road that the reactive power compensation amount that the present invention according to which section bus actual can need then allows this section of bus to use more greatly not drop into.
In sum, the present invention adopts double-bus three-phase balanced system to be compensated for as operational mode, economizes on resources to greatest extent according to actual service condition, and outside line wiring is simple, and device is provided with interlock function, avoids the situation of switching confusion.
Accompanying drawing explanation
Fig. 1 is the primary system figure of the on-the-spot reactive power compensation construction of the present invention.
Embodiment
Below in conjunction with accompanying drawing, 1 couple of the present invention is described in further detail:
Concrete technical scheme of the present invention is: as Fig. 1, the present invention uses in practice.By on 5 reactive power compensator cabinets parallel connection (non-actual switching state), two sections of buses in actual field construction, when which section bus needs reactive power compensation, the closing coil that this controller controls corresponding vacuum contactor carries out action, and does not need every section of bus all to connect 5 reactive power compensator cabinets.
The reactive power compensation system that double-bus controls, is made up of power unit, double-bus, output, reactive power compensation branch road, sampling section, controller and display section; Described double-bus is: I section bus, II section bus; Described reactive power compensation branch road comprises: two vacuum contactors, electric capacitor, discharge coil, discharge indicating lamp, lightning arrester, reactors, and wherein said vacuum contactor is the contactor connecting described reactive power compensation branch road and described double-bus; Wherein, described controller is connected with described sampling section, described display section and described vacuum contactor respectively.
Each reactive power compensation branch road is all furnished with vacuum contactor A and vacuum contactor B, is connected respectively with I section bus and II section bus.When I section bus put into by needs, control the vacuum contactor A action be connected with I section bus, make this branch road drop into I section bus; When II section bus put into by needs, control the vacuum contactor B action be connected with II section bus, make this branch road drop into II section bus.Because double-bus controls, the switching for each branch road adopts interlocking to arrange, and after the branch road that namely I section bus adopts drops into, II section bus must not use this branch road, and namely vacuum circuit-breaker A and vacuum circuit-breaker B can not be operated in closure state at the same time.When I, II two sections of buses all need the numerical value comparing reactive power needed for two sections of buses when throwing, large preferentially the throwing of demand.Adopt first to throw simultaneously and cut afterwards, the principle that rear throwing is first cut, avoids the frequent movement of same branch road.
Power unit adopts the Width funtion power module of 85-265VAC/DC, can meet the requirement of all secondary returnings of electric power system, adopt large bulk capacitance simultaneously, make the time of at least 2s still can be kept to be in normal operating conditions when Voltage Drop is zero.
Output adopts plug binding post to be connected with secondary circuit, changes very convenient, uses terminal to tighten solid screw means during external line simultaneously and fixes, reliably and conveniently.
Sampling section adopts two-way voltage sample and four road current samples, and the corresponding two-way electric current of every road voltage, meet the requirement that double-bus compensates, adopt fence type connecting terminal, safe, reliable and effective connection simultaneously.
Employing 320*240 in display section carries Chinese word library screen.Man-machine dialog interface: adopt Chinese interface; comprise the display of each physical quantity, the setting of Protection parameters, the query note of on off state, the setting of manual debug function (manually throw/cut) and each setting parameter of automatic switching and time display function, and the inquiry of the record such as switching action.
Double-bus three-phase balanced system is adopted to compensate.The B phase voltage of controller sampled I section bus and A, C phase current, simultaneously the B phase voltage of sampled I I section bus and A, C phase current.Controller, by the analytical calculation to sampling parameter, draws the reactive power needed for each section of bus, simultaneously according to the various setting parameters of controller setting, controls the action of vacuum contactor, load is carried out to the compensation of reactive power, improve the power factor of electrical network.
Feature of the present invention is, utilizes limited compensation equipment to meet the demand of two-way bus for reactive power compensation, economizes on resources to greatest extent, cut the waste.
The invention is not restricted to the above description to embodiment, the content that those skilled in the art disclose according to the present invention, the improvement that basis of the present invention need not be carried out through creative work and amendment, all should within protection scope of the present invention.
