【摘要】 近年来随着通信技术的发展，为了满足电力系统安全、稳定、高效生产的需求及电力企业运营走向市场化的需求，电力通信网的发展十分迅速。新设备的大量涌入使得电力通信网的智能化水平不断提高，功能日益强大，配置、应用也十分复杂。层出不穷的新产品、新功能、新技术及技术经济效益等诸多因素的影响，使可选择的设备越来越多，造成电力通信网络设备种类的复杂化。技术的发展使也促使人们的观念有了根本的改变，计算机网络技术与通信技术相互交融。电力通信网的业务已从调度电话、低速率远动数据传送扩展到高速、数字化、大容量的用户业务，例如计算机互联网、广域网、视频传送等。电力通信网的结构也已从单一服务于调度中心的简单星形方式发展到今天多中心的网状网络，以保证能为日益增长的电力信息传输需求服务。电力数据网必须保证电力系统安全、稳定、高效生产的需要，其中调度自动化信息、电能量采集信息、水情测报信息和 电网故障的分析等信息的安全性要求极高。面对这样一个要求高而且复杂的网络，采取一种有效的网络管理策略来保证电力数据网高效，可靠的运行就显得尤其重要。论文探讨了网络管理协议，对目前流行的SNMP、TMN及CMIP进行了分析。探讨了对网络管理的体系结构在此基础上对SNMP的管理信息库（MIB）、管理信息结构（SMI）和SNMP消息结构进行了比较详细的分析。然后对TMN、CMIP等协议及基于web的管理模式做了分析。电力数据网不仅要满足电力系统的通信需要，而且有可能要为公众服务，需求特别复杂。论文比较全面系统地分析了各种业务的特点和对网络的要求。作者根据贵州电力数据网的网络特点、网络业务的需求及目前网络管理的技术状况研究了这个网络的管理策略，提出了网络管理系统中各种网元管理的要求和网络管理性能的要求，强调网络性能管理系统对端对端的数据流传输的监控能力，网络性能应能够反映真实数据在传输的整个过程中的时延，丢包率等参数。提出了贵州电力网络安全管理策略和贵州电力网管人和规章制度策略，强调了管理人员的重要性。更多还原

【Abstract】 Nowadays, with the development of communications technology, in order to meet the requirements of high security, stabilization and efficiency of electric power system and meet the demand of marketization of operation of electric power corporation, the electric power communication network has developed rapidly. Wide utilization of new devices has led to higher intelligentization ,stronger functions and more complicated configuration and application of the electric power communication network.Emergence of numerous new products, functions, and technologies has largely increased our choices ,which leads to the complexation of the variety of electric power communications network. The technology’s progresses also influences people’s conception essentially, and make it possible to combine technologies of computer network with the technologies of communication. The services of electric power communication network have already expanded from telephone scheduling and transmitting data in low speed to digital user’s service with high speed and great capacity, such as computer internet, wide area network and video transmission, etc. Its structure has already developed from simple star topology ,which is used to serve schedular center, to today’s multicenter network to assure that the network can serve the requirement of increasing transmission of electric power information.The electric power data network must make sure that the electric power system has high security, stabilization and efficiency. The information of schedular automatization, electricity energy collection, water instance measure ,report and electricity network malfunction analysis requires very high security. With such strict requirements and a complex network, it is especially important to take an effective network manangement strategy to assure that the operation of electric power data network is effective and reliable.This paper has discussed network management protocol and analyzed today’s popular protocols such as SNMP, TMN and CMIP. I have probed into the archetecture of network management, and on the base of it I have analyzed the MIB and SMI of SNMP and the information structure of SNMP in detail. Then I have analyzed the TMN and CMIP protocols and management pattern based on web.The electric power data network is required not only to meet the needs of electric power system communication but also to serve the public. The requirements are very<WP=7>complex. This paper generally and systemically analyzed all kinds of services’ features and the requirements for network.Based on the features of network, requirements of network service and present network state in GuiZhou electric power data network, the author put forward the requirements of network managemant and performance in network management system , emphasizing the monitor ability of network performance managemnt system over end-to-end data stream transmission. He pointed out that network performance should be able to reflect the data transmission parameters such as delay, probability of dropped packets, and also network security management strategy of Guizhou electric power data network , meanwhile emphasizing the importance of talent management.更多还原
