Abstract
The invention belongs to the technical field of mobile emergency power supplies in a nuclear power plant and particularly relates to a medium-voltage mobile diesel power generator car for the nuclear power plant. The medium-voltage mobile diesel power generator car for the nuclear power plant comprises a diesel engine, a power generator, a power generator outlet circuit breaker, a starting storage battery and a mobile car, wherein the starting storage battery is used for starting the diesel engine, the diesel engine is connected with the power generator through a coupling, output of the power generator is transmitted to peripheral equipment through the power generator outlet circuit breaker, the diesel engine, the power generator, the power generator outlet circuit breaker and the starting storage battery are installed on the mobile car and mobile power supply can be realized. The medium-voltage mobile diesel power generator car for the nuclear power plant solves the technical problem that the requirement that the large motor load starting voltage drop is less than or equal to 25 percent under the power-off state of the nuclear power plant cannot be met; the power generator voltage drop caused by motor starting can be reduced and the on-load requirement that the large motor load starting voltage drop in the power-off state of the nuclear power plant is less than or equal to 25 percent is met.
Description
Technical field
The invention belongs to nuclear power plant's moving emergency power technique fields, be specifically related to press in a kind of nuclear power plant mobile diesel-oil electric generator wagon.
Background technology
Nuclear power plant's emergency source of electrical power is the necessary equipment of alleviating station blackout event, and after Fukushima, Japan event occurs, State Bureau of Nuclear Safety has issued " after Fukushima nuclear incident, nuclear power plant improves action current techique and requires (trying) ".According to the rules, nuclear power plant need to configure mobile emergency diesel powerplant.
According to usual diesel fuel generator set design regulation, substantially the parameter matching design equating with generator power by diesel engines at present, be that diesel engine and generator power ratio are less than or equal to 1:1, as 1:0.9,1:0.8, can not meet large motor load trigger voltage under nuclear station station blackout state falls≤and 25% band carries requirement, and the generator voltage that motor start-up causes falls excessive.
Particularly, the diesel-engine generator parameter generally adopting in prior art is as shown in the table:
In addition, the radiator of water tank volume that the larger requirement of diesel generation acc power matches is larger, and therefore, portable diesel-engine generator size is mainly limited by the size of diesel engine radiator radiator.Diesel-engine generator size of the prior art is difficult to meet the requirement of portable diesel-engine generator.
Summary of the invention
The technical issues that need to address of the present invention are: diesel-engine generator of the prior art, its diesel engine and generator power ratio are less than or equal to 1:1, can not meet large motor load trigger voltage under nuclear station off-position falls≤25% requirement, and the generator voltage that motor start-up causes falls excessive.
Technical scheme of the present invention is as described below:
In a kind of nuclear power plant, press mobile diesel-engine generator, comprising: diesel engine, electrical generator, generator outlet circuit breaker, starting storage battery and Trolley; Starting storage battery is used for starting diesel engine, diesel engine is connected with electrical generator by drive coupling, the output of electrical generator is transferred to external device by generator outlet circuit breaker, and diesel engine, electrical generator, generator outlet circuit breaker, starting storage battery are arranged on Trolley, can move power supply.
Described diesel engine and generator power be than between 1:1 ~ 1:2, if diesel engine and generator power are than being 1:1.4.
The beneficial effect that the present invention obtains is:
(1) in nuclear power plant of the present invention, press mobile diesel-oil electric generator wagon, its diesel engine and generator power are than between 1:1 ~ 1:2, reduce the generator voltage that motor start-up causes and fallen, meeting large motor load trigger voltage under nuclear station off-position falls≤and 25% band carries requirement;
(2) in nuclear power plant of the present invention, press mobile diesel-oil electric generator wagon, in the situation that not changing diesel engine power, by the power of suitable increase electrical generator, and electrical generator is less on the oad impact of whole unit, thereby can meet the requirement of mobile diesel-engine generator oad, for pioneering, extremely there is promotional value both at home and abroad.
