【摘要】：随着坚强智能电网建设的持续推进,在网络支撑能力方面对通信提出了更高的要求。承德电力通信网络在网络结构、业务承载能力、可靠性等方面暴露出了一些问题,无法满足不断增长的多样化的业务接入需求。作为电力系统的支撑部门,基础传输网络就是部门的生命线,对通信网络进行网络评估和优化至关重要。本文主要通过分析承德电力通信网络的缺陷,针对薄弱环节对通信网络优化方案进行设计和研究。首先从传输网、业务网、支撑系统、配电网四方面对承德电力通信网络进行了全面地自查和评估分析,构建了光传输可靠性分析模型和基于N-1原则的危险系数计算方法,对网络的可靠性进行了量化分析,找出了承德电力通信网的薄弱环节。通过对承德电力现有业务的带宽计算和未来业务发展的预测,估算业务需求带宽,并根据通信网络中存在的问题、新兴业务的发展需求、公司现有资源和未来投资能力,针对薄弱环节设计了承德电力通信网络优化方案,从而改善承德电力通信网络结构,增强业务承载能力、提高网络的安全性和可靠性。最后对方案实施后的成效进行了分析和展望：优化方案实施后整体效果显著,公司通信网络资源紧张的问题得到了缓解,网络结构合理、层次鲜明,基本实现双设备双路由双通道的可靠性要求,为承德电力的发展提供了基础保障；扩大了网络传输带宽和容量,能够满足承德电力在未来几年业务增长和多样化接入的需求。
[Abstract]:With the continuous development of strong smart grid construction, higher requirements for communication have been put forward in network support capability. Some problems have been exposed in Chengde electric power communication network in network structure, service carrying capacity, reliability, etc. Unable to meet the growing variety of business access requirements. As the supporting department of the power system, the basic transmission network is the lifeline of the department. It is very important to evaluate and optimize the communication network. This paper mainly analyzes the defects of Chengde electric power communication network, designs and studies the communication network optimization scheme aiming at the weak links. The supporting system and distribution network four aspects of Chengde electric power communication network are comprehensively investigated and evaluated, and the optical transmission reliability analysis model and the risk coefficient calculation method based on N-1 principle are constructed. The reliability of the network is analyzed quantitatively, and the weak links of Chengde electric power communication network are found. Through the calculation of the bandwidth of the existing service and the forecast of the future service development of Chengde Electric Power, the bandwidth of the service demand is estimated. According to the problems existing in the communication network, the development demand of the new business, the existing resources and the future investment ability of the company, the optimization scheme of Chengde electric power communication network is designed for the weak links, so as to improve the network structure of Chengde electric power communication. Finally, the effect after the implementation of the scheme is analyzed and prospected: the overall effect after the implementation of the optimized scheme is remarkable, and the problem of the shortage of communication network resources in the company has been alleviated. The network structure is reasonable, the level is bright, the reliability requirement of dual equipment, double route and double channel is basically realized, which provides the basic guarantee for the development of Chengde electric power, expands the transmission bandwidth and capacity of the network, To meet Chengde Electric Power in the next few years of business growth and diversification of access needs.
