Problems solved by technology

[0007] At present, in order to solve the problem that the real-time power will exceed the contract capacity, manual adjustment is generally used to avoid overlapping periods. However, due to the characteristics of the production line and the degree of coordination, this method cannot effectively avoid the peak power consumption in a timely manner.

Embodiment Construction

[0035] Such as figure 1 As shown, the actual power consumption of the whole plant and each production line is read from the substation (such as 110KV substation) through the PLC system, and the continuous 15-minute average power of the whole plant is calculated according to the actual data read, and this data is used as The basis for controlling the power consumption of each production line, and automatically take measures to reduce speed through PLC networking.

[0036] When the average power exceeds the set value for 15 consecutive minutes (for example, it is set to 24700KW), it needs to be adjusted to avoid overlapping power consumption peaks. The specific measures are:

[0037] Rolling part:

[0038] The rolling part includes two rolling lines to detect whether the rolling mill on the rolling line is in the last pass:

[0039] 1) If the rolling mills of the two rolling lines are not in the last pass, reduce the speed of the rolling mill of the rolling line with high real...

Abstract

The invention discloses a power-peak avoidance adjusting and controlling method for rolled wire and a galvanized wire production. The power-peak avoidance adjusting and controlling method is characterized in that the power is limited by comparing whether the average power in continuous time t exceeds a set value, and specifically, the adjustment and the control are carried out by adopting the measures of reducing the production speed of the rolled wire, limiting the increase of the power and switching a galvanizing groove for galvanizing to the heat preservation waiting state and the like. The power-peak avoidance adjusting and controlling method disclosed by the invention has the advantages that the adjustment and the control can be accurately carried out in time, the efficiency is high, and the power-peak overlapping period can be effectively avoided; the influence of the limited electric-quantity peak on the quality of a rolled wire product is furthest reduced in the adjusting and controlling period.

Description

technical field [0001] The invention relates to a power peak avoidance control method, in particular to a power peak avoidance control method for a rolling line and a galvanizing line used by a steel plate production enterprise. Background technique [0002] In terms of power supply, power supply companies (such as power supply companies) generally adopt a contract capacity power supply model with large power users. This model pays a certain monthly basic electricity fee according to the contract capacity. When the contract capacity is exceeded, penalty measures will be taken for the portion exceeding the contract capacity. [0003] The basis for judging whether the user's electricity consumption exceeds the contracted amount is the electricity demand, which is the average maximum value within a period of time (in the power industry, take an extra 15 minutes). Therefore, if it is not controlled, it will increase the cost of electricity consumption for large-scale electricit...
