【摘要】 根据《XY供电区“十一五”电网滚动规划及2015年展望》并结合近期XY市负荷发展情况,XY供电区2010年用电负荷预计达到1416MW。相关的输变电工程的建设,将作为XY地区220千伏形成环网供电的支点,这对整个XY地区的电力安全供应将起到有力的支撑保障作用,使XY地区的供电安全等级再上一个新台阶。变电站是电力系统的重要组成部分之一,其功能是实现对电能的分配、调度和传输控制。要确保变电站这些功能的顺利实现,关键是要建设高质量的变电站。变电站建设在电力系统的建设中起着举足轻重的作用。变电站施工质量的好坏直接影响着变电站的经济性、安全性和可靠性,进而影响着整个电力系统的稳定运行。质量控制作为变电站施工项目管理中最重要的一环,直接关系着工程进展、成本及企业的竞争力。变电站建设要实现“安全、优质、高效、零缺陷”的目标必须对工程前期规划、设计、施工过程、竣工验收等环节进行严格的质量预控。变电站的质量控制如何适应新形势的要求,如何提高质量控制水平,是摆在我们面前的一项新课题。本文从课题来源入手,首先分析了变电站质量控制的必要性,并结合变电站建设的质量目标,对国内外的变电站建设质量控制现状进行了初步分析。其次比较分析了变电站施工项目质量管理常用的统计方法,并详细阐述了变电站施工项目的工序质量控制内容,提出了加强变电站工程施工工序质量控制的办法;第三,为了更好的控制变电站建设质量,对变电站建设质量的控制方法进行了分析。控制方法的分析包括传统的统计方法在变电站建设质量控制中的应用和模糊综合评价方法在变电站建设质量控制中的应用。文章最后,对变电站建设的质量控制方法进行了总结与展望,并且进行了科学分析和客观评价,为XY供电公司变电站建设项目的质量控制提供了有效的理论依据。对进一步推动XY供电公司电网建设科学化、管理规范化,进而追求投资收益最大化,保证XY电网可持续发展具有重大意义。更多还原

【Abstract】 With recent development of power loads in Xinyang and the report of the eleventh five-year power network plan and prospect in 2015, loads in this supply area are forecasted to be 1416 MW in 2010. The above power transmission and transformation construct is the pivot of 220 kV ring network power supply in Xinyang district, which ensures the supply security and improves the secure supply to a higher grade.Power transform substations are one of the most important parts of power systems, and their functions are to distribute, to dispatch, to transmit and control power energy. Building high quality substation is crucial for the implement of these functions. Therefore, substation construct is significant in power system construct. The quality of substation determines the economy, security and reliability, and affects the stable operation of the entire power system. As the most important step in management of substation project under construction, quality control has a direct effect on the progress, cost and enterprise competitiveness. To reach the object that substation operates with security, high quality, efficiency and zero defects, the quality should be strictly monitored at every step such as project plan, design, construction process and project assessment and acceptance.At the beginning, this paper introduces the reason that we monitor power substation quality and compares the existing quality control theories considering the characteristics of power construction project. Then the usual statistical methods in substation construction management are analyzed. After the contents of in-process quality control are described in detail, the methods to strengthen in-process quality control are presented. To obtain higher quality of substation, the methods to control substation construction quality are analyzed, which include conventional statistical method and fuzzy comprehensive evaluation method. At last, the summary and scope on the control method of substation construction quality are provided.更多还原
