【摘要】：电力行业作为全社会经济发展的基础产业,承担着经济发展和人民安居乐业的重要任务,因此,它是国家经济发展的核心,在国家战略的制定中占有重要的地位。随着我国经济的飞速增长,全社会的电力需求急剧上升,电力供应不足时有发生,从而带来了许多损失和不良的影响。为此,国家不断扩大电力基础设施建设项目的规模,变电站的数量激增,但如何保证变电站安全运行,提供稳定安全的电能当前变电站日常生产管理管理面临的问题。变电站是电力生产运行中的重要组成部分,极大地影响着整个电网的安全和稳定性。变电站是连接用户和电网之间重要桥梁,对于电能安全、合理和稳定的传输发挥着至关重要的作用。只有保证用户安全、稳定地用电,才能确保可靠的社会生产。因此,在变电站生产作业管理中,研究作业过程中存在的风险,并进行评估和控制显得尤为必要。本文首先对国内外风险管理的理论和应用模式进行了总结,并根据我国的电力发展的趋势以及变电站管理的特点,分析了当前的变电站安全生产管理现状、面临的问题和原因,并提出了一定对策。其次为了构建变电站作业风险控制方法,介绍了PDCA循环模式的原理,以及PDCA循环在变电站作业管理应用的可行性,依据上述分析构建以PDCA为指导的变电站作业风险控制流程：首先是作业风险的识别、其次风险的评估与最后风险的控制。PDCA的管理模式是不断的循环和反复的,它明确了工作的方向是提高安全目标的评价值,不断地细化和调整分目标,再通过不断地循环将目标加以改善,最后以实现安全管理水平的提升。为了评估作业风险控制模式的应用效果,设计了有针对性的指标体系,利用层次分析法确定各指标权重,提出了基于模糊数学的变电站作业风险控制效果综合评价方法。最后本文以YD变电站为例,首先分析了其作业管理现状,并将本文提出的作业风险控制模式具体应用,对YD变电站作业风险进行设别、评估和控制。之后对YD变电站风险控制应用情况进行评估,发现应用过程中存在的问题。综上所述,变电站作业控制模式在经济性和安全性上都验证了具有良好的表现,对于风险的预防起到积极作用。
[Abstract]:As the basic industry of the whole social economy, the electric power industry shoulders the important task of economic development and people's living and working. Therefore, it is the core of the national economic development and plays an important role in the formulation of the national strategy. With the rapid growth of China's economy, the demand for electricity in the whole society has increased dramatically. Insufficient electricity supply has occurred, resulting in many losses and adverse effects. To this end, the state has constantly expanded the scale of electric power infrastructure construction projects, and the number of substations has increased sharply. But how to ensure the safe operation of substations and provide stable and safe electric energy is currently facing the problems of substation daily production management and management. The substation is an important part of the power production and operation, which greatly affects the security and stability of the whole power grid. The substation is an important bridge between the users and the power grid, which plays a vital role in the transmission of electrical energy in a safe, reasonable and stable way. Only by ensuring the safe and stable use of electricity can the reliable social production be ensured. Therefore, in the production management of the substation, it is particularly necessary to study the risk in the process of operation and to evaluate and control the operation. Based on the domestic and foreign risk management theory and application model are summarized, and according to our country's electric power development trends and characteristics of the substation management, analyzes the current situation, production safety management of substation is facing problems and causes, and puts forward some countermeasures. Secondly, in order to construct the risk control method of substation operation, introduces the principle of PDCA cycle model, and the feasibility of the PDCA cycle in the substation operation management application, on the basis of the above analysis the construction risk control process of substation operation under the guidance of PDCA: the first is to control the operational risk identification, assessment of risk and risk the last second. The management mode of PDCA is continuous and repeated. It clarifies the direction of work is to improve the evaluation value of safety objectives, constantly refine and adjust sub goals, and then improve the target through continuous cycle, so as to achieve the improvement of safety management level. In order to evaluate the application effect of operation risk control mode, a targeted index system is designed, and the weight of each index is determined by AHP. A comprehensive evaluation method of substation operation risk control effect based on fuzzy mathematics is put forward. Finally, taking YD substation as an example, the status of operation management is analyzed first, and the operational risk control mode proposed in this paper is applied to set up, evaluate and control the operational risk of YD substation. After that, the application of risk control in YD substation is evaluated, and the problems in the application process are found. To sum up, the operation control model of substation has proved to have good performance in economy and security, and plays an active role in the prevention of risk.
