Description
技术领域technical field

背景技术Background technique
当进行有序用电时,电力系统的用电信息采集系统平台监测用户负荷时数据存在延迟,实时数据需要召测并导出数据,再人工与所限负荷值进行比对。当工业用户发生超负荷运行时,只能人工告知其降负荷。对大型工业用户而言,没有决策依据,不能较好地分配各个车间的使用负荷。When orderly power consumption is carried out, there is a delay in the data when the power consumption information acquisition system platform of the power system monitors the user load. The real-time data needs to be measured and exported, and then manually compared with the limited load value. When industrial users are overloaded, they can only be told to reduce the load manually. For large-scale industrial users, there is no basis for decision-making, and the use load of each workshop cannot be well allocated.
现有技术的缺点:Disadvantages of the prior art:
(1)现有用户用电信息采集系统及时性、针对性无法满足工业用户的发展需求。用电信息采集系统处理数据庞大,数据传输及汇总存在延时问题,(1) The timeliness and pertinence of the existing user electricity consumption information collection system cannot meet the development needs of industrial users. The power consumption information acquisition system processes huge data, and there is a delay in data transmission and aggregation.
(2)用电信息采集系统仅可反映采集点数据,未细分企业的各个区域(车间)的用电情况,无法为企业用电提供有针对性用能管理的决策依据。(2) The electricity consumption information collection system can only reflect the data of the collection points, and does not subdivide the electricity consumption of each area (workshop) of the enterprise, and cannot provide a decision-making basis for the targeted energy consumption management for the enterprise's electricity consumption.
(3)社会电工从业人员普遍无法满足供电单位对工业用户规划的有序节能用电管理需求,存在电力能源供需与配置情况协调不一致、安全预警与过量生产存在时间差等问题,在一定程度上将会导致电力供需失衡,造成电力供需紧缺压力。(3) Social electrician practitioners are generally unable to meet the orderly energy-saving power management needs planned by power supply units for industrial users, and there are problems such as inconsistent coordination between power supply and demand and configuration, and time lag between safety early warning and overproduction. It will lead to an imbalance between power supply and demand, resulting in a shortage of power supply and demand.
