Description
Technical field
The present invention relates to a kind of distribution structure and control method of coaling system power consumption equipment.
Background technology
Coaling system is very important link of cogeneration power plant.Its technological process is mainly to utilize belt conveyor that coal is delivered to transfer station from Coal Stack Yard, is broken into compared with granule, and then utilizes belt conveyor to be delivered to main power house coal bunker.In whole process, power consumption equipment comparatively disperses, apart from each other (hundreds of rice is even farther), and most of power consumption equipment exists process concatenation relation.Therefore distribution and the control about coaling system is the problem that electric personnel pay close attention to always.
Traditional coaling system power distribution control method is, at transfer station, a low-voltage distribution chamber and PLC control room are set, and is responsible for the distribution of whole coaling system power consumption equipment and control.So just exist some drawbacks: a lot of to power, the control cables of power consumption equipment from switchgear house and control room, increased the investment of cable; Also increased the raising of difficulty and the corresponding project installation expense of cable laying simultaneously; And also brought because cable is compared with the long problem of pressure drop producing.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of reliable, distribution structure and the control method of the coaling system power consumption equipment that cost is low.
Technical scheme of the present invention: the distribution structure of this coaling system power consumption equipment, comprise the transfer station low-voltage distribution chamber that is arranged on transfer station place, described transfer station low-voltage distribution chamber is connected respectively with the Coal Stack Yard secondary switchboard that is arranged on the coal bunker secondary switchboard at coal bunker place and is arranged on Coal Stack Yard place, other power consumption equipments that coal bunker secondary switchboard and Coal Stack Yard secondary switchboard are all connected with one group of local mounted deduster control cubicle and arrange as required, connect one group of deduster power consumption equipment on deduster control cubicle.
Described deduster power consumption equipment comprise connection arranged side by side pulse control instrument, discharge valve, unload grey spiral, centrifugal blower, electric three passes scraper-trough conveyer and electric butterfly valve.
The control method that the distribution structure of coaling system power consumption equipment is carried out comprises:
Coal bunker secondary switchboard place arranges the PLC of coal bunker place control cubicle, gathers near the working signal of the power consumption equipment of coal bunker secondary switchboard;
Coal Stack Yard secondary switchboard place arranges Coal Stack Yard PLC control cubicle, gathers near the working signal of the power consumption equipment of Coal Stack Yard secondary switchboard;
Transfer station arranges the working signal that transfer station PLC control cubicle gathers near the power consumption equipment in transfer station low-voltage distribution chamber everywhere;
The working signal that aforementioned three places gather is sent to the host computer in the control room, transfer station place that is arranged on transfer station place by the Ethernet switch of ether communication network, in host computer, concentrate monitoring coaling system to need the operating state of the power consumption equipment of process concatenation, control;
The PLC of coal bunker place control cubicle and Coal Stack Yard PLC control cubicle are all connected with one group of Device Net module by DeviceNet bus, and Device Net module is arranged in deduster control cabinet for power distribution, gather the working signal of deduster power consumption equipment.
Between described Device Net module, by Device Net telecommunication cable, take chain type to connect.
Compared with prior art, the present invention has adopted rational distribution structure, makes from transfer station low-voltage distribution chamber to coal bunker and the power cable amount of Coal Stack Yard two greatly reduces.In addition, the present invention is provided with and is arranged on the spot near the deduster control cabinet for power distribution of equipment, make deduster control cabinet for power distribution also fewer to the cable consumption of deduster power consumption equipment (pulse control instrument etc.), reduced cable investment cost and relevant project installation expense.Reduced to a certain extent the quantity of low-voltage distribution panel simultaneously.The present invention has reduced the construction cost of whole system on distribution system to the controlling party rule of distribution, increase the reliability of system simultaneously.On controlling, improved the automaticity of deduster, make the control network of whole coaling system more clear succinct, utilize communication to substitute traditional hard connection, when reducining the construction costs, increased reliability and the extensibility of system.

Embodiment
Embodiments of the invention 1: the distribution structure of coaling system power consumption equipment of the present invention, as shown in Figure 1, comprise the transfer station low-voltage distribution chamber 1 that is arranged on transfer station place, described transfer station low-voltage distribution chamber 1 connects respectively (coal bunker and Coal Stack Yard are all the relative concentrated places of equipment) with the Coal Stack Yard secondary switchboard 3 that is arranged on the coal bunker secondary switchboard 2 at coal bunker place and is arranged on Coal Stack Yard place, other power consumption equipments 5 that coal bunker secondary switchboard 2 and Coal Stack Yard secondary switchboard 3 are all connected with one group of local mounted deduster control cubicle 4 and arrange as required, on deduster control cubicle 4, connect one group of deduster power consumption equipment.That is, twice electric power incoming lines of coal bunker secondary switchboard 2 and Coal Stack Yard secondary switchboard 3 these two secondary switchboards are by 1 power supply of transfer station low-voltage distribution chamber.Then by secondary switchboard, near the power consumption equipment it, powered.Therefore, from transfer station low-voltage distribution chamber 1 to Coal Stack Yard and the power cable amount of coal bunker two greatly reduce.
For adapting to need of production, at coal bunker and Coal Stack Yard place, more deduster can be set, it is the power supply of deduster power consumption equipment that the present invention has set up supporting deduster control cabinet for power distribution, as shown in Figure 2, deduster power consumption equipment comprise connection arranged side by side pulse control instrument 5, discharge valve 6, unload grey spiral 7, centrifugal blower 8, electric three passes scraper-trough conveyer 9 and electric butterfly valve 10.The present invention only need provide an electric power incoming line to deduster control cabinet for power distribution 1.And the power supply of deduster power consumption equipment is realized by deduster control cabinet for power distribution 4.Because deduster control cabinet for power distribution 4 is arranged on the spot near equipment, the cable consumption from deduster control cabinet for power distribution 1 to pulse control instrument etc. is just fewer like this, has reduced cable investment cost and relevant project installation expense.Reduced to a certain extent the quantity of low-voltage distribution panel simultaneously.
The control method that the distribution structure of coaling system power consumption equipment is carried out comprises:
