钢铁企业是耗能大户,也是用电大户,内部电力系统的安全经济运行直接影响企业的安全生产,同时电力消耗也是企业的主要生产成本支出之一。钢铁企业内部电网经济运行管理是一项实用性很强的综合技术,它与供电企业、电力系统的经济运行技术既有相同之处,但也存在一些根本的不同。这项技术是建立在坚持技术安全、经济合理的原则下,从内部电网规划、设计、施工,到投产运行、经营管理的各个环节,全过程执行节能、降耗、降成本的要求,通过大量的技术论证,选取合适的设备、优化运行方式、确定最佳主变负载率、调节分时段电量比例、提高功率因数、技术改造等,在保障安全生产的基础上,最大限度的降低电费支出,从而达到提高经济效益的目的。
Iron and steel enterprises are energy-hungry, but also power-hungry. The safe and economical operation of the internal power system directly affects the safety of enterprises. At the same time, power consumption is also one of the major production costs of an enterprise. The economic operation and management of power grids within the iron and steel enterprises is a highly practical and comprehensive technology. It has some similarities with the economic operation techniques of power supply enterprises and power systems, but there are also some fundamental differences. This technology is based on adhering to the principle of technical safety and economic rationality. From the planning, design and construction of the internal power grid to the operation and management of the power system and the requirements of energy saving, consumption reduction and cost reduction in the whole process, Of the technical arguments, select the appropriate equipment, optimize the operation mode, determine the optimal load factor of the main transformer, adjust the proportion of power in sub-periods, improve the power factor, technological transformation, etc., on the basis of ensuring safety in production, So as to achieve the purpose of improving economic efficiency.
