Description
Technical field
The present invention relates to a kind of high reliability pressurized-water reactor nuclear power plant station service electric power system.
Background technology
Traditional People's Republic of China's core professional standard《Pressurized-water reactor nuclear power plant station service electrical system design criteria》NB/
T20051-2011 proposes specific design criterion to the AC power supply system of pressurized-water reactor nuclear power plant station service：
（1）Compressed water reactor nuclear power station power use system should include the physically independent off-site power being connected with high-voltage fence of two-way（One
Road is main power source outside factory, and another way is off-site auxiliary power source）；Each power supply should be able to make all station-service equipments by its power supply
It can be further accelerated or start simultaneously when being switched to another power supply from a power supply.
（2）The on-site power being made up of two diesel generating sets of two-way independence is set for each monoblock.
Main power source outside factory：There is provided by transmission line of electricity outside factory, station-service equipment is by being connected to generator end breaker and main transformer
Between the power supply of station-service Working transformer, main power source can still be powered to station-service equipment outside factory during monoblock is stopped transport.
Off-site auxiliary power source：For Shuan Dui power plant, including circuit and by the line outside factory unrelated with transmission line of electricity all the way
Two auxiliary transformers of road parallel operation.Off-site auxiliary power source is that a pair of units share.
On-site power：Each monoblock is provided with the diesel generating set of two independent energy automatic starts.
Nuclear power plant's exchange house-service equipment is divided by its function as four classes：First, unit station-service equipment；Second, standing station-service is set
It is standby；Third, emergent station-service equipment, fourth, two monoblocks are public and plant area's electrical equipment.Wherein to reliability requirement highest
It is emergent station-service equipment, including safe level（1E）Electrical equipment and the station-service equipment for ensureing main equipment safety, wherein safe level
（1E）Electrical equipment is used for preventing, limiting, reducing the leakage of radioactive substance and alleviates damage sequence.Emergent station-service equipment is general
Powered by main power source outside factory, when main power source powers off outside factory, it is necessary to which off-site auxiliary power source is powered, when off-site power loses,
Need to be by the diesel-electric set electric supply of corresponding safe level station-service equipment series；
Electricity prison [2008] No. 43 texts of safety《On strengthening important power consumers power supply and the emergency power sources of self-preparing monitor configured pipe
The opinion of reason》It is required that：Superfine important power consumers possess three-way power condition of power supply, and two-way power supply therein should come from two
Different transformer stations, when any two-way power failure, three-way power can guarantee that independent normal power supply.
The reliable power supply of Nuclear Power Plant electricity consumption is one of factor that nuclear power station is capable of safe and stable operation most critical.2011
After Fukushima, Japan nuclear power plant accident, countries in the world are all improved to nuclear plant safety, especially emergent station-service equipment security
Requirement.Power monitoring department of China, which has been distinctly claimed nuclear power station service power, should meet that the power supply of superfine important power consumers will
Ask（Such as《On assigning notice-Fujian electricity prison safety (2011) 94 of CNNC Fujian Nuclear Power Co., Ltd.'s electric power safety supervise and examine opinion
Number》It is required that Fuqing nuclear power station service power should meet the power reguirements of superfine important power consumers）.Superfine important power consumers tool
Standby three-way power condition of power supply, safety standard are higher than《Pressurized-water reactor nuclear power plant station service electrical system design criteria》NB/T20051-2011
It is required that（The physically independent off-site power being connected with high-voltage fence of Nuclear Power Plant electricity consumption at least two-way, all the way to be main outside factory
Power supply, another way are off-site auxiliary power source）.
The large nuclear power station that China has gone into operation at present generally by the electric power that unit is sent by transformer boost to 500 kilovolts
After access power transmission network, by design standard, generally require more than 500 KVs 2 return, typically access two different 500 kilovolt
Transformer station.In addition, also configure 220 kilovolts of auxiliary substations, 220 KVs 1 are set to return or 2 times, access power network 220 kilovolts
Transformer station.
To make Nuclear Power Plant electricity system possess three-way power condition of power supply, the common practice of China's nuclear power station is auxiliary outside factory
Help power supply to be designed by 2 road independent loops, make the station-service electric forming three-way power of each nuclear power generating sets（All the way to be defeated outside factory
Electric line is powered through unit boosting main transformer, then through station-service Working transformer；Another two-way is the two-way unrelated with transmission line of electricity
Circuit and two auxiliary transformers by the line powering outside factory）.This method exists《Pressurized-water reactor nuclear power plant station service electrical system is set
Count criterion》On the basis of to add be all the way off-site auxiliary power source, it is two-way to make off-site auxiliary power source increase, although meeting superfine
The power reguirements of important power consumers, but shortcoming is to need increase by one to return, from circuit outside different factories of transformer station, to add and build
If difficulty and construction investment.
China's major part nuclear power is respectively positioned on coastal area, and wherein most is located remotely from the remote edge of populated area again
Sea region, build the difficulty in terms of new transmission line of electricity has line corridor.With Fujian Province's large nuclear power station（Abbreviation Y nuclear powers
Stand）Exemplified by, the nuclear power is building 4 million kilowatt nuclear power units, has gone into operation 2, has built 500 KV transmission lines 4 and has returned,
Pass through two passways for transmitting electricity（Each passage 2 returns 500 KVs）Two 500 different kv substations are accessed, have built 220
Kilovolt auxiliary substation one, plans twice 220 kilovolts of off-site auxiliary power sources, two different 220 kilovolt power transformations outside factory
Stand, but because line construction is obstructed, only build up at present 1 time, cause the station service only 2 road power supplys of each nuclear power generating sets, nothing
Method meets the power reguirements of superfine important power consumers.
