Description
Technical field
The utility model relates to a kind of from the motion tracking reactive power compensator.
Background technology
For the reactive power compensation of electric power system, only realize traditionally with filter.But more frequent for load variations, especially metallurgical, colliery electric power system are if only install harmonic filtering installation; Because its reactive power compensation is constant, therefore just caused when bus load is heavy the undercompensation of reactive power; And when load is light, idlely send electric power system again back to.Busbar voltage is raise.China adopts the method for " counter-rotating is just counted " at present to idle examination, promptly absorb the idle and anti-idle idle electric degree that all adds up that send, and causes power factor lower.
To the electric load characteristics of industries such as electric power, metallurgy, coal, both at home and abroad the dynamic passive compensation technology all to be studied, main type is divided into following several kinds:
(1) Static Type Dynamic Reactive Compensation Device (SVC): this device is thyristor-controlled reactor+filter (TCR+FC) mode.Its function has the smooth adjustment reactive compensation capacity, system response time is fast, and can comprehensive regulation harmonic wave.But because single thyristor withstand voltage level is lower; The type dynamic reactive compensation device is applied in 6kV and the above electric power system; Need to connect with a lot of thyristors, in the synchronous triggering of many thyristors with all press, control and aspect technical sophistication such as maintenance, reliability has much room for improvement; This plant area area is big, and the big needs of thyristor caloric value are assisted cooling device, the big special-purpose filter apparatus of outfit that needs of the harmonic content that self produces, and the cost high price is expensive.
(2) grouping switching capacitor mode: vacuum contactor (circuit breaker) switching mode; Can produce electric arc between switch contact during switching; Because of producing higher switching overvoltage and impulse current in the make and break process of capacitor loop; Be prone to produce arc reignition between contact, switch and capacitor safe operation are produced bigger influence.
(3) magnetic valve type compensation way: device is made up of compensation condenser and parallelly connected REgulatable reactor, through the adjusting of high impedance reactor magnetic flux, makes unnecessary capacitive reactive power capacitance balance in itself and the shunt capacitor.This is a kind of amelioration product of autotransducer compensation way, and because of its loss is big, operating cost is high, and governing speed is slow, and compensation range has certain restriction, belongs to filtering technique.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of can overcome above-mentioned defective from the motion tracking reactive power compensator, adopt magnet controlled reactor to carry out reactive power compensation, improve service behaviour.
The utility model solves the technical scheme that its technical problem adopted: a kind of from the motion tracking reactive power compensator; It is characterized in that; The KYN28 capacitor compensation cabinet that comprises the magnet controlled reactor cabinet and be arranged side by side with it; In the magnet controlled reactor cabinet magnet controlled reactor is set, the KYN28 capacitor compensation cabinet is connected the back and inserts electric power system with the magnet controlled reactor cabinet.KYN28 capacitor compensation cabinet and magnet controlled reactor are arranged side by side it, and described magnet controlled reactor can be connected DSP full-digital control system commonly used at present with the KYN28 capacitor compensation cabinet, and can connect the Long-distance Control output module, better meets user demand.
Vacuum contactor 2-2 in the magnet controlled reactor cabinet and the vacuum contactor 2-1 in the KYN28 capacitor compensation cabinet insert electric power system through isolating switch.
Vacuum contactor 2-2 is connected with current transformer, and current transformer connects magnet controlled reactor and voltage power-less controller respectively.Magnet controlled reactor cabinet and KYN28 capacitor compensation cabinet insert electric power system through isolating switch, guarantee the safe in utilization of whole device.
The beneficial effect that the utility model had is: the characteristics of utilizing magnet controlled reactor; Have that output harmonic wave is little, own loss is little (the magnet controlled reactor own loss is less than 1%), non-maintaining, simple in structure, remarkable advantage such as reliability Gao ﹑ Jia lattice Di Lian ﹑ floor space is little; Its inside is full static structure; Movement-less part, functional reliability is high, is desirable dynamic passive compensation, filtering and voltage adjuster.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1 from the motion tracking reactive power compensator; The KYN28 capacitor compensation cabinet that comprises the magnet controlled reactor cabinet and be arranged side by side with it; In the magnet controlled reactor cabinet magnet controlled reactor is set, the KYN28 capacitor compensation cabinet is connected the back and inserts electric power system with the magnet controlled reactor cabinet.Vacuum contactor 2-2 in the magnet controlled reactor cabinet and the vacuum contactor 2-1 in the KYN28 capacitor compensation cabinet insert electric power system through isolating switch.
It mainly is to filter humorous involving to electric power system output reactive power that capacitor, discharge coil and reactance in the KYN28 capacitor compensation cabinet gone.
Voltage power-less controller in the magnet controlled reactor cabinet is according to the reactive power sampling to electric power system; Be converted into pulse signal and be sent to magnet controlled reactor,, make the reactance value of magnet controlled reactor adjustable continuously through regulating the thyristor pilot angle of magnet controlled reactor control cabinet; Thereby the realization reactive power does not have the compensation of dead smooth; And utilize the own characteristic of magnet controlled reactor, have the characteristics of quick response, high reliability, the guaranteed output factor be stabilized in 0.98 and more than.Vacuum contactor 2-2 is connected with current transformer, and current transformer connects magnet controlled reactor and voltage power-less controller respectively, and the big electric current that collects is converted into little electric current, is convenient for measuring and plays a protective role.
