【摘要】：电力通信网络是为电力系统的安全稳定运行提供通信支撑服务的基础设施之一,对可靠性、稳定性、实时性上有非常苛刻的要求。K公司作为一家刚从市级升为省级的电网公司,其电力通信网络运营管理水平与新的可靠性考核指标体系存在差距。为了满足新形势下的新要求,亟需引入更力性的科学管理理论,探索具有更高效益的管理策略。首先,本文梳理了K公司电力信网的运营管理模式,针对K公司电力通信网运营管理与可靠性要求的现实矛盾,提出了在检修与缺陷管理、安全与反事故措施管理和通信调度与网管管理等三个方面存在改善空间。具体总结了K公司电力通信设备维修管理的特点,分析了K公司应急响应预案库现状,探究了K公司电力光缆故障处理方法的不足之处,并讨论了造成问题的主要原因。然后,运用可靠性原理,本文从理论上分析了对K公司电力通信网运营可靠性实施改进的可行性,并据此分别为K公司电力通信网运营管理层设计了能够改进管理方式、提高运营可靠性的三个参考策略。为了解决K公司在检修及缺陷管理方面落后的事后维修管理模式被动且低效的问题,本文提出并设计了基于RCM的优化电力通信设备维修方案的策略。该策略可以大幅改善K公司的设备维修管理水平,也能够避免传统的预防维修带来的维修过剩和维修不足的问题,并从一定程度上实现对设备故障率的可控。为解决K公司在安全与反事故措施管理方面应急预案审核评价工作不全面不合理的问题,提出并验证了基于随机Petri网的评估应急响应流程可靠性的策略。该策略将可填补K公司在应急响应流程可靠性评估方法上的空白,能大大提高应急响应预案审核工作的效率,而又能节省大量应急演练带来的时间、经济成本。为解决K公司在通信调度与网管管理方面光缆故障诊断准确率低、及时性差的问题,提出并验证了基于概率神经网络的快速诊断电力光缆故障的策略。该策略可以减弱在故障分析和处理的过程中通信调度员主观因素方面的过多影响,并使得提前进行针对性的抢修资源调配成为可能,有助于缩减故障恢复时间。最后,本文通过识别和分析可靠性改进策略实施过程中的关键需求,为策略的实施保障针对性提出了数据采集、组建专家团队和立项实施的建议。
[Abstract]:Power communication network is one of the infrastructure to provide communication support services for the safe and stable operation of power system. There are very harsh requirements in real-time. K company as a power grid company has just been upgraded from the municipal level to the provincial level. There is a gap between the power communication network operation management level and the new reliability assessment index system. In order to meet the new requirements under the new situation, it is urgent to introduce more powerful scientific management theory. First of all, this paper combs the operation and management mode of K company electric power communication network, aiming at the realistic contradiction between the operation management and reliability requirements of K company electric power communication network. The improvement space of maintenance and defect management, safety and anti-accident measure management, communication dispatch and network management is put forward. The characteristics of K company electric power communication equipment maintenance and management are summarized in detail. This paper analyzes the present situation of the emergency response plan database of K Company, probes into the shortcomings of the power optical cable fault treatment method of K Company, and discusses the main causes of the problem. Then, the principle of reliability is applied. This paper theoretically analyzes the feasibility of improving the operational reliability of K company's electric power communication network, and designs a management mode for K company's electric power communication network management. Three reference strategies to improve operational reliability. In order to solve the problem of K company in maintenance and defect management backward after-maintenance management mode passive and inefficient. This paper puts forward and designs the strategy of optimizing power communication equipment maintenance scheme based on RCM, which can greatly improve the equipment maintenance management level of K Company. It can also avoid the problem of maintenance surplus and insufficient maintenance caused by traditional preventive maintenance. In order to solve the problem that the emergency plan audit and evaluation work in safety and anti-accident measures management of K company is not comprehensive and unreasonable. The strategy of evaluating the reliability of emergency response process based on stochastic Petri net is put forward and verified. This strategy can fill the blank of K company's reliability evaluation method of emergency response process. It can greatly improve the efficiency of emergency response plan audit, but also save a lot of time brought by emergency drills, economic cost. In order to solve K company in communication scheduling and network management in optical cable fault diagnosis accuracy is low. The problem of poor timeliness. A probabilistic neural network based strategy for fast fault diagnosis of power optical cables is proposed and validated, which can reduce the excessive influence of subjective factors of communication dispatchers in the process of fault analysis and processing. And make it possible to allocate the resources in advance, which is helpful to reduce the time of fault recovery. Finally, this paper identifies and analyzes the key requirements in the implementation of reliability improvement strategy. For the implementation of the strategy to ensure targeted data collection, the formation of expert teams and project implementation recommendations.
