Abstract
The invention provides a method for supplying and distributing important loads in a first-stage load of a control room.A basic load rate of a UPS (uninterrupted power supply) design capacity is selected to be below 40% in an online uninterrupted power supply system, the UPS adopts double mains supply power supply, an automatic conversion function is arranged in the UPS, non-important loads are separated from important loads, the power supply of the non-important loads is removed from the UPS, and the non-important loads are changed into I-section or II-section power supplies for direct power supply. The invention is easy to implement and expand, can greatly improve the reliability of a power supply system, ensures the normal supply of UPS commercial power, has the internal automatic conversion of the UPS obviously superior to a spare power automatic switching device between external bus sections, can avoid severe accidents of equipment serious damage caused by power failure superior to a control system, powerfully ensures the power supply of important loads, effectively reduces the accident rate and reduces the purchase cost of spare parts.
Description
Technical field
The invention belongs to energy power supply-distribution system field, belong to particularly to the control system in a kind of control room
The power supply and distribution method of important load in first order load.
Background technology
At present, the control system in each main production unit control room of domestic metallurgical works on-site belongs to
Important load in first order load, its power supply mode many employings UPS (on-Line UPS electric power system)
Power supply mode.But, find through long-term production practices, owing to UPS original design capacity exists mostly
Irrational phenomenon, the violation of power supply supply mode and the reason of load adjustment, had a strong impact on for distribution in addition
Stability, cause UPS electric power system Frequent Troubles, control system dead electricity, and UPS once damage, will
Directly result in the visual plant power-off such as DCS (electric station dcs), unit chaser, cause a lot of
Equipment badly damaged serious accident, UPS restores electricity to unit and recovers properly functioning needs more than 8 hours.
Summary of the invention
It is desirable to provide a kind of easy to implement and extension, reliable, it is avoided that control system dead electricity,
Ensure that important load is powered, reduce the power supply and distribution method of important load in the control room first order load of accident rate.
To this end, the technical solution that the present invention is taked is:
The power supply and distribution method of important load in a kind of control room first order load, it is characterised in that:
1, on-Line UPS electric power system i.e. UPS is used for important load in control room first order load
Power supply mode, the base load rate of UPS design capacity selects below 40%, to avoid impact load to UPS
Impact, prevent UPS and be switched to bypass or the risk of directly tripping operation.
2, UPS takes double mains supply to power, the internal band auto-conversion function of UPS, when I section of power supply due to
When fault is stopped power supply, II section of power supply realizes conversion automatically inside UPS.
3, carry out load classification, insignificant load is separated with important load, and by the power supply of insignificant load
Reject from UPS, change other service poweies into and power.
The invention have the benefit that
The present invention easy to implement and extension, the reliability of electric power system can be greatly improved, when I section of power supply due to
When fault is stopped power supply, II section of power supply realizes conversion automatically inside UPS, it is ensured that the normal confession of UPS civil power
Giving, the internal conversion automatically of UPS is substantially better than the backup auto-activating device between external bus section, can avoid being better than controlling
The equipment badly damaged serious accident that system dead electricity causes, strong guarantee important load is powered, and effectively reduces
Accident rate, reduces spare parts purchasing expense.
Detailed description of the invention
As a example by certain integrated iron and steel works' dry coke quenching electric station ups system, the UPS that this enterprise is used at present
Capacity is 3kVA, and single mains-supplied, its on-load is 3 operator stations, 1 engineer station, 2 electricity
Gas shielded backstage, 2 station servers, and rear 1 office computer increased, totally 9 equipment.
Being mainly industrial computer computer in 9 equipment, every equipment is pressed 0.4kW and is calculated, general power time at full capacity
3.6kW, alreadys more than the capacity of online UPS, does not has capacity of short circuit to spend in advance.This rate of load condensate all reaches 80% at ordinary times
Above, once over loading or short-circuit impact will cause electric power system fault, have a strong impact on the stable operation of system.
To this end, the power supply and distribution method that the present invention is taked is:
1, the base load rate of UPS design capacity selects below 40%, and i.e. selecting rated capacity is 10kVA
UPS, to meet the needs of capacity of short circuit, stability that ups system power is effectively ensured.
2, UPS takes double mains supply to power, the internal band auto-conversion function of UPS, when I section of power supply due to
When fault is stopped power supply, II section of power supply will not be damaged simultaneously, so that II section of power supply is internal real at UPS
The most automatically change, it is ensured that the normal supply of UPS civil power.
3, carry out load classification, the power supply of insignificant load is separated with important load, will insignificant load
1 office computer power from UPS reject, change II section of power supply into and directly power, so that it is guaranteed that other 8
The normal power supply of platform visual plant and safe operation.
Claims (1)
1. the power supply and distribution method of important load in a control room first order load, it is characterised in that:
