【摘要】 电网调度是电力安全生产管理的核心,对电网运行实行“统一调度、分级管理”的原则。在保证电网安全、稳定运行的基础上,提高电网调度管理水平,是调度部门必须认真研究的课题。科学的调度可以提高公司的经济效益,最大限度地保证对用户多供电、供好电,以强大的电网和有效的管理提高为客户服务的能力。本文首先阐述了盐城电网的规模,盐城电网的运行特点;系统研究了盐城电网的电力电量情况,对电量和负荷的增长情况进行合理的预测分析。其次,本文通过运用电力系统分析综合程序对盐城电网进行建模和计算。通过调节各节点的参数进行不同运行方式、不同负荷下的潮流计算,以此分析研究并解决盐城电网存在的问题和薄弱环节。最后本文对盐城电网的运行优化和合理规划提出了建议和措施。更多还原

【Abstract】 Power grid dispatch is the core of safe electricity producing and management, obeys the principle of“dispatch centrally, manage by classification”.On the basis of securing power grid and operating stably, improving management level of grid dispatch is a important task that dispatch department should research.Scientific dispatch can increase economic benefit of company, provide more and better quality electricity for more customs,improve service ability for customs with powerful grid and efficient management.Firstly, this paper descibles grid scale and grid operation character of Yancheng district; research power sum of Yancheng grid systematically; predict and analyze increasement of power sum and load rationally.Secondly,this paper models and calculates Yancheng grid through electrical system analyzing program,carry out flow calculation under different operation ways and different loads through modifying node parameter,then rearch and solve problems and weak part existing in Yanchen grid.Last, this paper gives some suggestion and measures for optimizing Yanchen grid operation and layouting rationally.更多还原
