Abstract
The utility model discloses a dynamic reactive power compensator, including the electric wire netting, the output of electric wire netting respectively with voltage sensor and current sensor's input electric connection, voltage sensor and current sensor's output all with the input electric connection of controller, the output of controller respectively with the input electric connection of alarm device and IGBT dc -to -ac converter, IGBT's the output and the input electric connection of wave filter, the output connected load circuit of wave filter. The utility model discloses an installation current sensor and voltage sensor gather electric wire netting internal load signal in real time, and work as the circuit and break down, control and alarm devices work, control inverter can be transformed into the alternating current to the direct current to effective filtering is carried out to frequency through beyond this frequency point of frequency dot OR of wave filter specific frequency in to the power cord, finally transmits to load circuit, improves the transmission of electricity quality.
Description
Technical field
This utility model relates to reactive power compensation technology field, is specially a kind of dynamic reactive compensation device.
Background technology
Dynamic passive compensation generating means; i.e. STATCOM; have another name called static reacance generator; the reactive power that this device is mainly used in compensation network frequent fluctuation; suppress electrical network flickering harmony ripple; improve the power factor of electrical network; improve power supply quality and the service efficiency of power distribution network; and then reduction via net loss; be conducive to extending transmission line of electricity service life current various idle and harmonic compensations equipment in, for suppressing harmonic wave, the method for compensating reactive power mainly has two classes: a class is installing harmonic reactive compensating apparatus; Another kind of is that power electronic equipment itself is transformed; it is made not produce harmonic wave while realizing self function; do not consume idle yet; or as required it is carried out PFC; but in existing device busy, it is good not that the protective measure of circuit is made, it is impossible to effectively the electric current to electrical network of automatization and voltage condition are controlled in real time; for this, we design a kind of dynamic reactive compensation device, are used for solving the problems referred to above.
Utility model content
The purpose of this utility model is in that to provide a kind of dynamic reactive compensation device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of dynamic reactive compensation device, including electrical network, the outfan of described electrical network is electrically connected with the input of voltage sensor and current sensor respectively, the outfan of described voltage sensor and current sensor is all electrically connected with the input of controller, the outfan of described controller is electrically connected with the input of alarm device and IGBT inverter respectively, the outfan of described IGBT is electrically connected with the input of wave filter, and the outfan of described wave filter connects load circuit.
Preferably, described controller adopts idle compensating control.
Preferably, described wave filter adopts band elimination filter or high pass filter.
Preferably, described alarm device includes LED flash alarm lamp and buzzer siren.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by installing current sensor and voltage sensor, electrical network internal load signal is carried out Real-time Collection, and transmit signals to idle compensating control, work as circuit malfunctions, control alarm device work, control inverter and direct current energy is transformed into alternating current, and by wave filter, the frequency beyond the frequency of characteristic frequency in power line or this frequency is effectively filtered out, obtain the power supply signal of a characteristic frequency, or eliminate the power supply signal after a characteristic frequency, it is finally transmitted to load circuit, improve transmission of electricity quality.
