随着我国经济的迅猛发展,能源供需矛盾日益突出,尤其是现代化企业生产超负荷用能现象严重,为此,能源管理部门常常对这些进行拉闸处理。有些生产过程由于其特殊性,不允许随意拉闸,因此,这些单位必须对其下属部门的能耗进行控制,机动灵活地组织生产,使总负荷不能超出能源管理部门的指标。另外,还须对压力、流量等参数实时监控,保障安全生产。 为了解决日益紧张的能源供需矛盾,提高工业生产企业的生产管理水平,使其能根据总负荷及压力状态,有效地组织压峰工作及生产指挥工作,本文介绍一套如何设计并实施的能源实时监测系统。 一、系统功能和主要技术参数 1、对整个单位的一级能源进行监测 (1)电能:在总进户线各台控制柜中取瞬时电压、电流、功率、功率因素、电量累计值 (2)蒸汽:在进口各管首中取瞬时压力值、流量累计值。 (3)压缩空气:在空压站各空压机中取瞬时压力值、流量累计值。
With the rapid economic development in our country, the contradiction between supply and demand of energy has become increasingly prominent. In particular, the modern enterprises are overloaded with energy and can produce serious problems. Therefore, energy management departments often carry out gate-discharge treatment. Due to their particularity, some production processes are not allowed to be randomly opened. Therefore, these units must control the energy consumption of their subordinate departments and organize their production flexibly so that the total load can not exceed the energy management department’s targets. In addition, the pressure, flow and other parameters must also be monitored in real time, to ensure safe production. In order to solve the increasingly tense contradiction between supply and demand of energy and improve the production management level of industrial production enterprises so that they can effectively organize peak pressure work and production command according to the total load and pressure conditions, this article introduces how to design and implement energy real-time Monitoring System. First, the system functions and main technical parameters 1, the entire unit of a primary energy monitoring (1) Electric energy: the total incoming line control cabinet take instantaneous voltage, current, power, power factor, total power value Steam: The first in the import of each tube instantaneous pressure value, the cumulative value of traffic. (3) compressed air: air compressor station in the air compressor to take instantaneous pressure value, total flow value.
