Description
Technical field
The utility model belongs to factory's hydroelectric field, particularly relates to a kind of flowed fluctuation water condition stable electric generation device.
Background technique
Hydroelectric power utilizes to be positioned at the water that eminence has potential energy and to flow to lower, and wherein contained potential energy converting and energy is become the kinetic energy of water turbine, relending water turbine is motive force, and pushing generator produces electric energy.Electrical power generators Capability Requirement is greater than load power, but actual power power and load (comprising power generating equipment from electricity consumption and line loss) power is consistent forever because merit can not disappear, also can not have more without foundation, only can be equal.If water flow fluctuates, electrical power generators ability can be caused inadequate, cause undertension, till bearing power drops to generator power, or generator overload protection, not so can damage generator.In practical application; water flow may at any time in fluctuation, as in industrial production because equipment is numerous, pipeline is complicated; there is the situation of individual plants shutdown maintenance; also have the situation that peak electricity consumption of hiding in daytime and evening runs, thus in water circulation flow at any time in change, if do not consider that this changes; do not take certain measure; water turbine is impossible stable operation just, causes generator powered quality unstable, have the occasion of requirement will directly to cause dying young of generation engineering to power generation stability.
One of current known solution is incorporated into the power networks, grid-connected rear generator can motor synchronizing work, water can will become electric energy to grid transmission by defeated dynamic transformation of energy, spread of voltage can not be caused because of the change of load, current, but its supporting synchronous device, station service fast switching device cost are high, be unfavorable for that factories and miness are promoted, water flow can not be overcome completely simultaneously and to fluctuate the interference brought, easily cause the accident exceeding generator motor synchronizing regulating power and off-the-line; Another kind method installs water turbine governors additional, it can regulate the rotating speed of turbine-generator units automatically, it is made to remain on running in rated speed permissible error, to meet the requirement of electrical network to frequency quality, but water turbine governors and match equipment cost high, be unfavorable for that factories and miness are promoted, this method can not avoid the situation of generator step-out equally completely, easily causes off-the-line when exceeding water wheels governor regulating power.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of flowed fluctuation water condition stable electric generation device, overcomes the defect that existing solution cost is high, rate of fault is high.
The utility model realizes like this, a kind of flowed fluctuation water condition stable electric generation device, comprise high-level reservoir, low level production technology millpond, between high-level reservoir and low level production technology millpond, main road pipeline and bypass duct are set, main road pipeline installs generator set near low level production technology millpond, bypass duct installs regulating valve, for regulating the current in bypass duct according to low level production technology millpond water level.
Further, described main road pipeline is of a size of the main road section of tubing diameter needed for the minimum water consumption of actual production process determining.
Further, low level production technology millpond arranges level sensor, level sensor is connected to a single-chip microcomputer input end, and the output terminal of described single-chip microcomputer is connected with a motor, and the output terminal of motor connects regulating valve, and described regulating valve is electric valve.
Compared with prior art, beneficial effect is the utility model: under not affecting original water supply condition, and adopt main water route to generate electricity, bypass adjust flux is to optimization.
The utility model solves the technological scheme that its technical problem adopts:
Basis is novel to be transformed before original pipeline water inlet turbine, and install bypass duct, main road pipe water mouth bore presses least quantity duct size, and bypass duct installs regulating valve, and controlling opening of valve adapts to flowed fluctuation.The utility model is not affecting under original water supply condition, and adopt the generating of main road pipeline, bypass duct adjust flux, has cost low, the advantage of failure rate is low.
Accompanying drawing explanation
Fig. 1 is the apparatus structure schematic diagram that the utility model embodiment provides;
Fig. 2 is the circuit structure block diagram of control valve.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1, a kind of flowed fluctuation water condition stable electric generation device, comprise high-level reservoir 1, low level production technology millpond 6, main road pipeline 2 and bypass duct 3 are set between high-level reservoir 1 and low level production technology millpond 6, main road pipeline 2 installs generator set 5 near low level production technology millpond 6, bypass duct 3 is installed regulating valve 4, for regulating the current in bypass duct according to low level production technology millpond 6 water level.Main road pipeline 2 is of a size of the main road section of tubing diameter needed for the minimum water consumption of actual production process determining, how to determine that the pipe diameter of minimum water consumption is conventional technology, does not repeat herein.
See Fig. 2, low level production technology millpond arranges level sensor, level sensor is connected to a single-chip microcomputer input end, and the output terminal of described single-chip microcomputer is connected with a motor, and the output terminal of motor connects regulating valve, and described valve is electric valve.
Generated electricity by main road, stability of flow, under now ensureing the prerequisite that main road is stable, the deficiency of low level production technology millpond flow will inevitably be caused, bypass duct is adopted to pass through regulating valve, ensure that the water yield of low level production technology millpond meets process water, thus can not the problem of stable electric generation under solving flowed fluctuation water condition.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
