Description

Industrial enterprise power utilization load optimizing system
Technical field
The invention belongs to enterprise's electric load scheduling field, a kind of industrial enterprise power utilization load optimizing system is particularly provided.
Background technology
The industries such as iron and steel, electrolytic aluminium, copper smelting are the industries that power consumption is large, the two-part rate system price of what enterprise customer's the charge of electricity of these industries performed is large commercial power, total electricity charge form primarily of power cost, basic charge as per installed capacity (also known as electrical capacity charge or demand charge) and the adjustment electricity charge.Power cost is according to the power consumption of user at spike Pinggu day part, the electricity charge calculated according to spike Pinggu rate; Basic charge as per installed capacity is with transformer station's expense that " maximum demand " is collected this month 40% expense collected of transformer capacity (or by); The adjustment electricity charge are the expenses of carrying out rewards and punishments according to of that month power factor size.
Requirement is the average power in the requirement cycle.
In the requirement cycle, the computation period of requirement, China is 15 minutes in the general provision requirement cycle.
Maximum demand is the maximal value of requirement in the time interval of specifying, and is generally a payment cycle.
Requirement account form, sliding, from any time, measure the method for requirement by the time recursion being less than the requirement cycle, recurrence time is the slippage time, and the slippage time can be 1,3,5,15 minute (or random time of 1 to 15 minutes); Interval type, from any time, measures the method for requirement by given requirement cycle recursion.
Impact load, some large-scale electric equipments of enterprise, as Recent Development for Large Scale Electric Arc, large-scale blooming mill, smelting furnace, electrolytic furnace, all kinds of shape rolling mill, continuous cold and hot-slabbing mill etc., single-machine capacity is large, amplitude, the frequency of the variation of its active power are all comparatively large, and this type load is referred to as impact load.
By the moon tracing analysis of business electrical load, finding electricity consumption high load capacity period very limited, is generally several hours to tens hours, and is exactly that the high load capacity of this limited period of time makes this month maximum demand exceed certain numerical value.The reason causing power load to raise is exactly the operation of impact load, and the superposition of impact load sometimes makes load higher.The short time impact load being less than 15 minutes can not cause requirement to raise; but these main equipments such as electric arc furnaces, smelting furnace, electrolytic furnace, milling train generally only can not open a few minutes; once start can not be shut down to reduce load, shutting down the loss caused can be larger.
The scheduling major part of current enterprise electric system is just according to information such as trend, load, warnings, carry out phone scheduling, not deep to the understanding of requirement and maximum demand, also corresponding means are lacked to observe the relation of current loads and requirement, load adjustment scheme cannot be made in time, reduce the impact on requirement; And a lot of local power supply department does not allow that enterprise directly reads the maximum demand information in Source of Gateway Meter, can only artificial timing meter reading, the moon maximum demand payment that enterprise can only provide according to power supply department, cannot know when, which workshop or equipment result in the increase of this month maximum demand, also just cannot provide useful information for the production adjustment of next month.
