Description
Technical field
The present invention relates to provide to nuclear power station the energy-storage system storing unit of reserve emergency power supply, and a kind of means of defence of nuclear power station power supply storing unit anti-flooding.
Background technology
Nuclear power station (Nuclear Power Plant) is to utilize nuclear fission (Nuclear Fission) or nuclear fusion (Nuclear Fusion) to react the generating plant of the power generation electric energy that discharges.
In order to protect the health of nuclear power station staff and nuclear power station surrounding resident, the principle of depth defense is all adopted in the design of nuclear power station, construction and operation, provide multiple protective from equipment, measure, to guarantee nuclear power station the output power of reactor is effectively controlled, and can various disasteies appear, such as earthquake, tsunami, flood etc., or the artificial fire that produces, blast etc., also can guarantee reactor fuel assemblies is cooled off fully; And then guarantee that the discharging to environment does not occur radiomaterial.The depth defense principle generally comprises five layers of defence line, the ground floor defence line: well-designed, make, construction, guarantee that nuclear power station has superior hardware environment, the program of Erecting and improving and strict system, to the systematic education and training of nuclear power station staff, set up complete nuclear Safety Culture; Second layer defence line: strengthen operational management and supervision, in time the correct abnormal conditions of processing are fixed a breakdown; The 3rd layer of defence line: in the severely subnormal situation, the control and protection system of reactor can in time and effectively move, to prevent equipment failure and human error and then to develop into accident; The 4th layer of defence line: under accident conditions, in time enable the nuclear plant safety protection system, comprise various engineered safeguards features, in order to the power management in the reinforcement accident, Accident prevention enlarges, with the integrality of protection nuclear power station three road barriers; The layer 5 defence line: just in case the extremely impossible accident that occurs occurs, and leak with radioactivity, should in time enable inside and outside all emergency systems of factory, make great efforts to alleviate accident to the impact of surrounding resident and environment.
Safety system all adopts autonomous device and redundant arrangement, so that security system can be antiseismic and be moved in other rugged surroundings.
No matter power supply arranges or moves as the power source of nuclear power station operation, all should embody the theory of depth defense.For realizing the high reliability of nuclear power station power-supply system, all should have emergency power pack to the consumer of some particular importance or the equipment of specific (special) requirements, carry out simultaneously multiplicity, the setting of independence ground, cause the unavailable of emergency power pack to avoid that common mode failure occurs.
The emergency power system of nuclear power station and normal power source system consist of station service electrical system together jointly, for consumers all in the factory provides safe and reliable power supply.Emergency power pack must guarantee to provide power supply at the emergent safety equipment for nuclear power station during accidental conditions, the accident conditions or behind the accident conditions, to carry out security function.Because the singularity of Nuclear Power Station safety is so the designing requirement of its power-supply system should be much higher than other industry.
Nuclear power station is provided with the multiple tracks redundant power, comprise the dedicated emergency power supplys such as primary power outside the factory, off-site auxiliary power source and emergent stationary diesel engine, Each performs its own functions for each power supply, mutual cooperates again simultaneously, not only various informative, and arrange layer by layer, multiple redundancy provides reliable power supply for electric nuclear power station to greatest extent.
At present, the station service electrical system method of operation of nuclear power station is as follows:
(1) under normal running (operation) conditions, the distribution system of whole station-service equipment is powered through HV Auxiliary Transformer by the 26kV bus;
(2) when unit normally moves, the 26kV bus is powered by main generator;
When (3) main generator is shut down, then send electricity through main-transformer to the 26kV bus by the 400/500kV electrical network;
(4) if the 26kV bus loses power supply or loses HV Auxiliary Transformer, namely lose primary power outside the factory, then the 220kV electrical network to the safety aid facility power supply that must move, makes reactor maintain hot shutdown condition through auxiliary transformer;
(5) if primary power and off-site auxiliary power source all lose power supply outside the factory, then to emergent station-service power devices, make reactor enter the cold shut state by emergency diesel dynamo (unit is equipped with two emergency diesel dynamos);
(6) when any emergency diesel dynamo is unavailable, then replaced by the 5th diesel engine, carry out the function of emergency diesel dynamo, to emergent station-service power devices.
Yet fixed emergency diesel-oil machine has certain limitation.This be because, drive its generator operation at stationary diesel engine, when the Conversion of Energy of diesel oil is electric energy, must be by the pure air in the stationary diesel engine cylinder, after will filtering with after high-pressure atomization diesel oil that atomizer ejects fully mixes, pushing piston is descending, each cylinder is successively acting in certain sequence, thereby drives crankshaft rotating.By the rotor that rotarily drives generator of stationary diesel engine, utilize " electromagnetic induction " principle again, generator will be exported induction electromotive force, through the load circuit generation current of closure, thereby realizes electricity generate function.In the above-mentioned power generation process, must could realize by air and fully mixing of high-pressure atomization diesel oil.When in the situation such as flood, tsunami, rubble flow lower time, the electrical system of stationary diesel engine might lose efficacy because of water logging, oil supply pipe, compressed air piping might rupture because of external impact force, the diesel engine body might be because impulsive force and structure deforms, these all can cause the stationary diesel generator to start, and then emergency power pack can't be provided.
Therefore, in the situation that other power supplys lose, fixed emergency diesel-oil machine as the final emergency power pack of nuclear power station, owing to having determined it, its storing unit own characteristic can not resist water logging disaster (such as flood, tsunami, typhoon tide etc.), when the extreme disaster of super design reference occurring, fixed emergency diesel-oil machine is easy to lose power supply, can't provide the power demand that the reactor core waste heat is discharged and Spent Fuel Pool cools off for nuclear power station, and this will cause nuclear power station to produce catastrophic consequence.
In recent years, along with battery technology progress and development, accumulator especially lithium battery and lithium phosphate battery owing to have that volume is little, quality is light, voltage is high, power is large, self discharge is few and the advantage such as long service life, become gradually the main flow equipment of electrical source of power, yet ripe cell capacity below 200Ah, can not satisfy the request for utilization of used in nuclear power station accumulator energy-storage system far away usually in the market.Therefore, need again research and development to be applicable to the high-capacity battery energy-storage system of nuclear power station, the multiple power source such as emergency power supply loses in main outside factory, off-site auxiliary power source and the factory, and the 5th emergency diesel dynamo is can not normal starting the time, the accumulator energy-storage system can be realized fast, provide emergency power supply to reactor safety facility and spentnuclear fuel system in time, keeps nuclear power station and is in a safe condition.
