Description
Technical field:
The utility model relates to a kind of dynamic passive compensation and filter, is specifically related to the BN-SVG static reacance generator.
Background technology:
Domestic reactive power compensator is to adopt capacitor to carry out reactive power compensation basically, and the power factor (PF) after the compensation is generally about 0.8-0.9.What BN-SVG adopted is that power module carries out reactive power compensation, and the power factor (PF) after the compensation is generally more than 0.98, and this is state-of-the-art power technology in the world at present.Reactive power compensation need be finished instantaneous, if the overlong time of compensation does not have when can cause this to want idle, and the undesirable condition that had come on the contrary when should not want idle; BN-SVG just can finish single compensation in the time of 5-20 millisecond.
Summary of the invention:
The purpose of this utility model provides a kind of BN-SVG static reacance generator, and it does not adopt jumbo electric capacity, inductance component, but series reactor limits idle output current; The high order harmonic component that filtering device produces; Two voltage sources are coupled together.When inductance value increased, filtering offset current high order harmonic component effect was better, but the device offset current reduces.Realize the conversion of quadergy by the HF switch of device for high-power power electronic, thereby make reactive power compensation technology produce qualitative leap: response speed is faster, and fail safe is higher, the compensate function variation, and harmonic content is extremely low, and floor space is less.
The purpose of this utility model is achieved in that
The BN-SVG static reacance generator, its composition comprises: series resistance case, series reactor, actuating section, power section, control section, described series resistance case connects series reactor, and described series reactor connects actuating section; Described actuating section connects power section, and described power section connects control section; Described actuating section is made up of contactor, bypass resistance, voltage transformer, current transformer, lightning arrester; Described power section adopts drawer-type structure design, compact conformation; Link units comprises radiator, insulated gate bipolar transistor, dc capacitor, copper bar, discharge resistance, trigger board in the described power section, asking for can power module.
Beneficial effect:
1. the utility model can the balance electrical network, and compensation network is needed idle, in parallel and the electrical network, is equivalent to a variable reactive current source, and its reactive current can be controlled flexibly, the reactive power that self compensating system is required.The utility model is core with the high-power voltage source inverter of three-phase, its output voltage is by connecting the transformer connecting system, keep with frequency, homophase with system side voltage, determine character and the capacity of power output by the relation of regulating its output voltage amplitude and system voltage amplitude, when its amplitude greater than the system side voltage magnitude time output capacitive reactive power, the output perception is idle during less than the system side voltage magnitude.
The utility model has solved the problem of the idle interference shunt capacitor of harmonic wave switching compensation with imitating.
The utility model can suppress or the improvement harmonic wave cleaning power grid environment according to customer requirements.
The utility model makes the reactive power compensation technology response speed faster, and fail safe is higher, the compensate function variation, and harmonic content is extremely low, and floor space is less.
The utility model utilization can turn-off, high-power, high-frequency power electronic device: as IGBT, composition is from the commutation bridge circuit, be connected in parallel on the electrical network through reactor, regulate bridge circuit in real time and exchange side output voltage amplitude and phase place, or directly control its ac-side current, make the bridge circuit absorption or send the reactive current that meets the demands, realize the dynamically purpose of control of dynamic passive compensation, voltage, estimate installing whole heating, design has special air channel, rationally chooses the heat radiation air quantity.
When the utility model inductance value increased, filtering offset current high order harmonic component effect was better.
