Abstract
The invention belongs to the technical field of mine power supply, and in particular relates to a power supply system with a gas power generation station as an emergent security power-supply point of a coal mine. The main load of the coal mine is as follows: a power supply loop consisting of a gas drainage pump, a main water pump and a main fan is supplied by an I-section bus bar of a mine power substation; the other power supply loop is directly supplied by the bus bar of the gas power generation station; and the outgoing line of the gas power generation station is butted joint with the II-section bus bar of the mine power substation to carry out grid-connected operation. When a peripheral power grid is tripped, the gas power generation station can directly supply power to the main load so that the power supply system regularly operates, underground safety accidents caused by power failure are reduced, and the safe production of the coal mine is ensured.
Description
Technical field
The invention belongs to the mine power supply technical field, be specifically related to the electric power system of gas electricity station as the emergent emergency power supply point in colliery.
Background technology
Whether mine drainage and gas exhaust normally are two main factors that influence Safety of Coal Mine Production, and whether mine power supply reliably directly has influence on the pump drainage of mine drainage and fire damp.Present stage, Coal Production requires double circuit power supply, and also there is single circuit power supply in the little colliery of part, though most of colliery is a double circuit power supply, a lot of two circuit upper level power supplys all are to take from same power supply point.When electric power system breaks down, will cause the mine power supply full cut-off, long like power off time, also can cause major accidents such as fire damp seriously transfinites, the mine water pump house is flooded, particularly more be prone to take place this type of power outage at thunderstorm season.For guaranteeing the normal operation of mine visual plant and accessory system, to avoid causing the accident and heavy economic losses, mine sets up emergent emergency power supply point just to seem most important.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the electric power system of a kind of gas electricity station as the emergent emergency power supply point in colliery is provided, make Safety of Coal Mine Production more secure.
The technical solution adopted for the present invention to solve the technical problems is: the gas electricity station is as the electric power system of the emergent emergency power supply point in colliery; Comprise mining area main sub station 1, gas electricity station 2, feed pump switchgear house 3, main fan switchgear house 4 and gas pump house switchgear house 5; It is characterized in that; Mainly a load current supply circuit of gas suction pump, feed pump and main fan of mine is supplied with by the I section bus of ore deposit electric substation 1; Another current supply circuit is directly supplied with by the bus at gas electricity station 2, and the outlet at gas electricity station 2 is docked with the II section bus of ore deposit electric substation 1 and is incorporated into the power networks.
Described gas electricity station 2, low all low pressure disconnection devices of installing and automatic synchronizing paralleling device on its outlet switchboard.
Described gas electricity station 2 is furnished with the high concentration gas gas holder.
The invention has the beneficial effects as follows: as the emergent emergency power supply point in colliery, on the one hand, utilize the Device in Gas generating of the original directly emptying of mine, practiced thrift the energy, reduced the discharging of greenhouse gases to the gas electricity station; On the other hand, for mine safety production provides reliable power supply guarantee, thereby reduced because the downhole safety accident that has a power failure and cause ensures Safety of Coal Mine Production, the coal supply mine belt comes good economic benefit, social benefit and safety benefit.
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Description of drawings
Fig. 1 is the power supply sketch map of gas electricity of the present invention station as the electric power system of the emergent emergency power supply point in colliery.
Among the figure:
1, mining area main sub station, 2, the gas electricity station, 3, the feed pump switchgear house, 4, main fan switchgear house, 5, gas pump house switchgear house.
The specific embodiment
Shown in accompanying drawing 1; The gas electricity station that the present invention proposes is as the electric power system of the emergent emergency power supply point in colliery; Comprise mining area main sub station 1, gas electricity station 2, feed pump switchgear house 3, main fan switchgear house 4 and gas pump house switchgear house 5; It is characterized in that; Mainly a load current supply circuit of gas suction pump, feed pump and main fan of mine is supplied with by the I section bus of ore deposit electric substation 1, and another current supply circuit is directly supplied with by gas electricity station 2, and the outlet at gas electricity station 2 is docked with the II section bus of ore deposit electric substation 1 and is incorporated into the power networks.
Described gas electricity station 2, low all low pressure disconnection devices of installing and automatic synchronizing paralleling device on its outlet switchboard.
Described gas electricity station 2 is furnished with the high concentration gas gas holder.
In the present embodiment; Power supply capacity according to gas electricity station 2; Operating load in conjunction with mine gas drainage pump, main fan and feed pump; The one telegram in reply source (being called for short the I loop) of gas suction pump, main fan and feed pump is supplied with by the I section bus of the 10KV of ore deposit electric substation (or 6KV or 400V), and by 10KV (or 6KV or 400V) the bus direct-furnish at gas electricity station 2, the outlet at gas electricity station 2 is docked with the II section bus of ore deposit electric substation 1 and is incorporated into the power networks in another telegram in reply source (being called for short the II loop).When mine normally moved, because the network system of gas electricity station 2 electric power systems and mining area main sub station 1 is incorporated into the power networks, the main load gas suction pump of mine, main fan and feed pump were directly supplied with by gas electricity station 2, so power supply is stable.Break down can not normal power supply the time when the II section bus of ore deposit electric substation 1 or gas electricity station 2, above-mentioned main load is by the I section bussed supply of ore deposit electric substation 1.
When peripheral electric power system tripping operation causes two sections buses of ore deposit electric substation 1 all not have electricity; Low all low pressure disconnection devices and the automatic synchronizing paralleling device installed on the 2 outlet switchboards of gas electricity station in time move, and make gas electricity station 2 drive gas suction pump, main fan and these three main load independent operatings of feed pump.As long as there is Device in Gas to be fed to gas electricity station 2, generating set is confessed after the generating with regard to turning round generating, and capital equipments such as gas suction pump, main fan and feed pump are not had a power failure.So just can reduce the colliery because of the loss that the frequent tripping operation of peripheral electric power system causes, further reduce security risk.
The load matching problem, during less than power load, the order that load side Reduction of Students' Study Load lotus stops equipment is like gas electricity station 2 electric set electric supply abilities: stop feed pump or main fanning earlier, after stop gas suction pump, just preferentially ensure the power supply of gas suction pump.
After peripheral electric power system restored electricity, 2 outlet switchboards action in gas electricity station made it to be incorporated into the power networks with mining area main sub station 1 network system, recovers original powering mode.
In order further to improve reliability, near gas electricity station 2, build a 1000M
3The gas gas holder, the inside stores high concentration gas, can be used as an emergent source of the gas that replenishes, to guarantee the normal operation at gas electricity station 2.
