石化行业的特点要求保持连续性生产,生产装置供电的可靠性必须得到保证,且生产环境比较特殊,对供配电系统提出了较高的要求。大型石化企业采用何种供配电方式,既能满足生产需要,又能使供配电系统安全、可靠、经济及合理地运行是亟需解决的问题。本刊特邀从事石化行业电气设计的工程技术人员就相关问题提出看法和展开讨论,希望能给广大读者带来有益的参考,也欢迎感兴趣的读者与行业人士积极参与。 The characteristics of the petrochemical industry require continuous production, the reliability of the power supply of the production plant must be guaranteed, and the production environment is rather special, putting forward higher requirements for the power supply and distribution system. What kind of power supply and distribution mode should be adopted by large-scale petrochemical enterprises can not only meet the production needs, but also make the power supply and distribution system safe, reliable, economical and reasonably run, which is an urgent problem to be solved. Articles invited to engage in petrochemical design of electrical engineering and technical personnel to put forward their views and discussions on the relevant issues in the hope that readers can bring useful reference, but also welcome interested readers and industry professionals to actively participate.
