摘要
在节能减排的背景下,工业企业电网自备电厂机组和用能设备呈现单机容量不断增大的趋势,在提升企业能效水平的同时,也给企业电网的安全稳定运行带来新的挑战。针对工业企业电网面临的功率平衡控制难题,提出工业负荷参与系统有功平衡的调节方法。并引入快关汽门作为安稳控制的一种手段,提出有功协调控制系统总体方案和实现路径。通过提升负荷和电源的快速响应能力,实现工业企业电网正常生产和事故紧急状态下的精细化控制,为提高企业电网安全稳定运行水平和企业经济效益提供技术支撑。在某电解铝企业电网的工程实践表明,该方法是切实可行的。
In the context of energy conservation and emission reduction,self-supplied power plant units and energy-using equipment of ithe ndustrial enterprise power grid show a trend of increasing single-unit capacity.While improving the energy efficiency of enterprises,it also brings new challenges to the safe and stable operation of the enterprise power grid.This paper looks at the power balance control problem faced by industrial enterprise power grid,and proposes an adjustment method for industrial load to participate in active power balance and introduces a fast closing valve as a means of stability control.Finally,an overall scheme and implementation path of an active coordination control system are proposed.The rapid response of power and load enables fine control of the industrial enterprise power grid normal production and accident emergency,and provides technical support for improving the safe and stable operation level of the enterprise power grid and enterprise economic benefits.Engineering practice in an electrolytic aluminum enterprise power grid shows that this method is feasible.
