Research On High Reliability Technology And Management Of Power Distribution System In Large Stadiums And Gymnasiums

With the strong support of the state for sports,the demand for large-scale stadiums is increasing.The reliability of distribution system is very important for the operation of stadiums.However,due to various reasons,there are still many problems in the distribution system of large-scale stadiums in China,and its reliability needs to be improved.In order to improve the reliability of power distribution system in large stadiums and gymnasiums,minimize the frequency and scope of blackouts,and reduce the cost of blackouts,through in-depth investigation and research,this paper adopts five methods,including investigation and research,literature research,induction and summary,case analysis and comparative analysis,and adopts conditional probability model and life cycle management model as the theoretical basis.From the three aspects of optimal design and selection of distribution system,setting value of complete selective protection and life cycle management based on project management mode,the four main problems existing in distribution system of large stadiums in China are mainly solved,such as one-sided pursuit of high reliability,failure to achieve high reliability,step-over tripping and extensive management.At the same time,combined with Zhuhai Sports Center distribution system management experience,the following conclusions are drawn.The distribution system of large-scale stadiums and Gymnasiums in China should adopt high reliability technology and life cycle management at the same time,strengthen the overall management of the planning,research,project establishment,design,bidding,construction,commissioning,operation and maintenance of the distribution system of large-scale stadiums and gymnasiums to ensure the high reliability of the distribution system of large-scale stadiums and gymnasiums,so as to achieve the overall optimization and maximum value.The effect and the highest standard in case of power failure should not occur.This paper can not only guide the operation,maintenance and transformation of the existing distribution system of stadiums and gymnasiums,but also guide the planning,design and construction of the proposed distribution system of stadiums and gymnasiums,and improve the availability of the distribution system.It can also provide reference for the construction and management of important transportation,communication hub and distribution system often used in important international public places.
