Description

A kind of three-phase load unbalance regulating system
Technical field
This utility model belongs to low-voltage distribution field, is related to the regulation of three-phase load unbalance, and especially a kind of three-phase is born Lotus imbalance regulating system.
Background technology
In current low-voltage network, most of platform area is all using three-phase transformer, but exists big in low-voltage network Amount single-phase load, simultaneously because the time asynchronism of single-phase load skewness weighing apparatus and input is so that three-phase load is uneven Weighing apparatus is objective reality.In many cases, three-phase load unbalance is to cause line loss and endanger the main of distribution transforming life-span Reason.Rational adjustment three-phase load unbalance, for improving quality of voltage, reduces line loss, and the prolongation distribution transforming life-span has weight The meaning wanted, thus also using the operation that electric equipment is safe and reliable.
Existing area's distribution transforming three-phase load unbalance, investigates and analyses dynamics by great load in artificial real work, Often load current is tested, separately phase sequence is adjusted, due to the irregularities of electricity consumption, manual working intensity is big, Adjustment needs to have a power failure, and affects power supply reliability.
Existing area's distribution transforming three-phase load adjusts imbalance automatically, relies primarily on reactive power compensator or with phase-shifting method is The device of principle, to solve, is not the three-phase load unbalance on actual solution platform area circuit, and device works in itself and needs Consume energy, adds additional loss.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, a kind of three-phase load unbalance is provided to adjust System, realizes three-phase load autobalance, and method is simple, easily carries and realizes.
This utility model solves technical problem and be employed technical scheme comprise that:
A kind of three-phase load unbalance regulating system, opens including a three-phase balancing concentrator, multiple three-phase balancing Pass, a set of three-phase balancing main station system, three-phase balancing concentrator is installed on by distribution transforming, and three-phase balancing switch has been installed on At the shaft tower of service conductor, wirelessly it is connected between three-phase balancing concentrator and three-phase balancing switch, three-phase balancing concentrator Wirelessly it is connected with three-phase balancing main station system, three-phase balancing concentrator controls three-phase balancing switch, receive three-phase simultaneously The remote measurement of balancing switch upload, remote signals;Three-phase balancing main station system receives the distant of three-phase balancing concentrator upload Survey, remote signals, also issue control command to three-phase balancing concentrator, to control three-phase balancing to switch.
And, pass through ZigBee wireless telecommunications between three-phase balancing concentrator and three-phase balancing switch.
And, pass through GPRS wireless telecommunications between three-phase balancing concentrator and three-phase balancing main station system.
Advantage of the present utility model and good effect are:
1st, the system can carry out real-time monitoring to the distribution transforming of platform area, and three-phase balancing concentrator detects three-phase imbalance Afterwards, through data analysiss, three-phase balancing concentrator sends dependent instruction and switchs to respective three-phase balancing, and three-phase balancing is opened After pass is connected to instruction, is similar to and manually falls load, execution be switched to target separate on, many table apparatus switch over operation in real time, from And realize three-phase load autobalance, simply, easily carry and realize.
2nd, the system can effectively reduce the intensity of front man, provides work efficiency, reduces line loss, extends The distribution transforming life-span has great importance, thus also using the operation that electric equipment is safe and reliable, lifting power supply enterprise's image.
Brief description
Fig. 1 is installation and the connection diagram of the system.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following examples are simply retouched The property stated, be not determinate it is impossible to limit protection domain of the present utility model with this.
A kind of three-phase load unbalance regulating system, as shown in figure 1, include three-phase balancing concentrator, a Duo Gesan Phase balancing switch, a set of three-phase balancing main station system.Three-phase balancing concentrator is installed on by distribution transforming, and three-phase balancing is opened Close and be selectively installed at the shaft tower of service conductor according to load condition.Three-phase balancing concentrator and three-phase balancing are opened MANET between pass, using ZigBee wireless communication technique and 2.4G DSSS spread spectrum, safe and reliable, three-phase balancing Gathered data is transferred to three-phase balancing concentrator by switch, and three-phase balancing concentrator receives the switch collection of three-phase balancing Data, three-phase balancing concentrator passes through GPRS wireless telecommunications, transfers data to three-phase balancing main station system, shows distribution transforming Electric current, voltage, the electric current of P, Q, COS numerical value, degree of unbalancedness and service conductor, voltage, P, Q, COS numerical value and current institute symbolic animal of the birth year Not.
Three-phase balancing concentrator controls three-phase balancing switch, the remote measurement of reception three-phase balancing switch upload simultaneously, Remote signals;Three-phase balancing main station system receives the remote measurement of three-phase balancing concentrator upload, remote signals it is also possible to issue Control command to three-phase balancing concentrator, to control three-phase balancing to switch.
Three-phase balancing concentrator is analyzed to real time data judging, when distribution transforming three-phase load unbalance degree reaches 15% More than (can set), and continue five minutes (can set), statistics peak load separate on all switch loads combined result, meter Calculate suppose commutation after degree of unbalancedness, issue instructions to after taking optimum peak load separate on respective switch, multiple stage three-phase adjust Balance cock real-time bringing onto load not power-off is separate from the currently separate target that switches to, thus realizing three-phase load adjust automatically.
If peak load is separate above, do not have three-phase balancing switch here separate, will be separate for second largest load After switch above takes optimum combination, three-phase balancing concentrator issues instructions to multiple stage three-phase balancing and switchs real-time bringing onto load Not power-off is separate from the currently separate target that switches to, thus realizing the minimum degree of unbalancedness of platform area distribution transformer load.
Above-described is only preferred implementation of the present utility model it is noted that ordinary skill for this area For personnel, on the premise of conceiving without departing from utility model, some deformation can also be made and improve, these broadly fall into this reality With new protection domain.
