【摘要】：变电站是电力系统中重要的组成部分,起着汇集、分配电能的作用,变电运行作为供电企业劳动生产的第一线，其管理水平的高低，直接影响系统整体的运行状况。在电力全球化、企业竞争日趋激烈的今天，推行电力运行精益化管理是变电站提升运行管理水平的一种思维革新。目前，这方面的理论研究大都将重点集中在变电站的自动化系统建设上，且基于变电站管理主要依赖于经验管理的现状，将精益化思想应用到变电站的运行管理中并建立统一、明确考核体系的研究成果还较少。同时，国网公司以及各省市电力公司出台的相关细则是变电站日常管理的基本依据，在制度内的创新局限性大，这在一定程度上也限制了这方面更深入的研究。精益化管理理论的核心特点是减少浪费，做到“少而精”，这也是研究变电站运行管理的主要目的。运行值班员工一个小小的失误或者误操作都可能会给变电站乃至国家造成不可挽救的损失，因此，如何最大程度做到日常运行管理的规范化，提高工作效率，保证变电站的正常运行以及电网的安全生产，是本文主要研究的问题。此外，以人为本的思想在精益化方法中贯穿始终，该方法除了能够应用在将站内工作流程进行精益化，还能应用于将其内部人员行为的规范转化成一套可执行的、有绩效价值的、可衡量的监督考核体系。基于人为因素强的特点，变电运行人员在执行工作中难免有所偏差，只依靠大量的检查或是相关的规范细则无法保证执行力。有必要从人性化的角度出发，建立员工的监督考核体系，做到奖惩严明，从而确保变电站内工作的可控与能控。本文针对上述问题，对精益化方法在变电站运行管理中的应用进行了研究分析，在探讨精益化管理思想发展、内涵、基本内容及核心工具的基础上，绘制了变电站设备巡视、倒闸操作、班组建设等流程的工作流程图，提出问题所在的同时分析了相对应的精益化建设方案；以人为本，建立了变电站员工的监督考核体系。结合丰泉变电站运行管理现状，将精益化方法应用于该站，对相关运行管理流程进行了精益化建设，建立员工的监督考核体系，，用实践验证了本文所分析方案的合理性,进一步体现精益化方法在变电站管理中的有效性与实用性。本文可为今后变电站运行管理精益化建设提供借鉴。
[Abstract]:Substation is an important part of electric power system, which plays the role of collecting and distributing electric energy. As the first line of labor production in power supply enterprises, the operation of substation directly affects the operation of the whole system. With the globalization of electric power and the increasingly fierce competition of enterprises, it is a thinking innovation to promote the level of operation management of substation to carry out lean management of electric power operation. At present, most of the theoretical researches in this field focus on the construction of substation automation system, and based on the current situation that substation management mainly depends on experience management, lean thinking is applied to substation operation management and unified. Clear appraisal system research results are still relatively small. At the same time, the relevant rules issued by the national power company and the provincial and municipal power companies are the basic basis for the daily management of substations, and the innovation in the system is very limited, which to some extent limits the further research in this area. The core feature of lean management theory is to reduce waste and achieve "less but better", which is also the main purpose of substation operation management. A small mistake or misoperation of the staff on duty may cause irreparable losses to the substation or even the country. Therefore, how to standardize the daily operation management to the greatest extent and improve the working efficiency, The main problem of this paper is to ensure the normal operation of substation and the safe production of power grid. In addition, the people-oriented approach runs through the lean approach, which can be used not only to lean the workflows within the station, but also to translate the norms of the behavior of its insiders into an executable set. Performance value, measurable monitoring and evaluation system. Based on the strong characteristics of human factors, it is inevitable for substation operators to deviate from each other in carrying out their work, and only relying on a large number of inspections or relevant rules and regulations can not guarantee the execution power. It is necessary to set up the supervision and assessment system of staff from the angle of humanization, so as to ensure the controllability and controllability of the work in the substation. In this paper, the application of lean method in substation operation management is studied and analyzed. On the basis of discussing the development, connotation, basic content and core tools of lean management, the inspection of substation equipment is drawn. The flow chart of switching operation, shift construction and other flow charts is put forward, and the corresponding lean construction scheme is analyzed while the problem is put forward, and the supervision and assessment system of substation staff is established based on the principle of "people-oriented". Combined with the present situation of operation and management of Fengquan substation, the lean method is applied to the station, and the relevant operation management process is constructed, and the staff supervision and assessment system is established. The rationality of the scheme analyzed in this paper is verified by practice. Further reflect the effectiveness and practicability of lean method in substation management. This paper can provide reference for the lean construction of substation operation management in the future.
