Background technology
Elevator is the potential energy load, in nonequilibrium condition operation (as be lower than the semi-load of up during operating mode and greater than the semi-load of descending during operating mode) and repeatedly in the retarding braking process, will produce a large amount of potential energy and kinetic energy (industry claims that this operating mode is a generating state).During the operation of elevator generating state, to satisfy the rotating speed under the given frequency, consequent power conversion is that the anti-dc-link capacitance group side that is poured into the elevator drive frequency converter is assembled the formation high voltage direct current behind the electric energy to motor by anti-dragged brake.Elevator speed is fast more, stop is high more, it is frequent more to play braking, and the electric energy that converts to is then many more.When the electric energy of accumulation surpasses certain limit, can cause system-down even burn, also can produce a large amount of hot driving contaminated environment.
Address this problem two kinds of schemes arranged at present:
First dynamic braking scheme: insert high-power resistance in drive system, with consumed energy.Studies show that the direct electric energy that consumes on brake resistance of elevator accounts for the 35%-46% of elevator wastage in bulk or weight electric energy;
It two is energy feedback schemes: adopt the active inversion technology, at the external energy feedback inversion transformation of elevator drive frequency converter DC side brake unit the energy feedback grid.
First kind of scheme cost is lower, and be technical simple.Shortcoming is that waste of energy is unfavorable for building energy-efficient society, and because brake resistance work will be distributed a large amount of heat and pernicious gas, contaminated environment;
Second kind of scheme energy-saving effect is obvious, sends electrical network synchronously back to after the energy that elevator produces can be reverse into alternating current.Shortcoming is that the quality of power supply (as waveform, synchronous etc.) of feedback grid is subjected to necessarily doubting and if the big large-scale elevator of quantity all may threaten to the safety of electrical network to electrical network loopback electric energy.In addition, energy feedback scheme will increase the buying expenses of elevator customer and user self not had actual energy-conservation being benefited.
