应用于大型工业企业的动态快速负荷减载
|
摘要
电力供应的可靠性对于生活中所有的领域都是相当重要的,对于大型的工业企业,例如石化炼化企业,钢铁冶炼等行业尤其如此。由于停电事故造成的损失不仅仅包含生产流程中产生的物料损失成本,还包含了生产中断带来的损失成本,潜在的设备损坏带来的成本,以及对环境甚至人身安全带来的影响。很多大型的工业企业,都具有热电联产的能力,可以在产生电能的同时通过余热产生工厂生产过程中需要的蒸汽。如何利用工业企业的发电能力。在电网发生大的扰动甚至形成孤岛时保障工业企业的生产,尽可能的降低电力故障带来的损失是工业企业面临的重要课题。本文结合通用电气(GE)在工业领域实施动态快速负荷减载的经验,描述了实施动态快速负荷减载系统所要面对的关键问题,并简要介绍了GE所提供的动态快速负荷减载方案。
The reliability of power supply is very important for all areas of life, especially for large industrial enterprises such as petrochemical refining companies and steel smelting. Losses due to power outages include not only the cost of material lost in the production process, but also the cost of lost production disruptions, the cost of potential equipment damage, and the impact on the environment and even on personal safety. Many large industrial enterprises have the capacity of cogeneration, which can generate electricity and generate steam required for the production process of the factory. How to use the power generation capacity of industrial enterprises. In the event of large disturbances in the power grid and even the formation of isolated islands to ensure the production of industrial enterprises, it is an important issue for industrial enterprises to reduce the losses caused by power failures as much as possible. This paper combines GE's experience in dynamic fast load shedding in the industrial field, describes the key issues to be implemented in the implementation of dynamic fast load shedding systems, and briefly introduces the dynamic fast load shedding scheme provided by GE.
