The Research On Sdh Evaluating Specification In Guangdong Power Grid

With the power grid construction of safe, reliable, stable operation put forward higher requirements, communication system as guarantee power grid scheduling, administration important platform and means, its position is more and more important. Optical communication network in power system communication network as the backbone network, carrying the power required for all important service, its reliability is a big problem in the operation and maintenance personnel. Strengthen pair of optical communication equipment testing, targeted test, can be more in-depth, comprehensive understanding of the various manufacturers to provide communications equipment related to performance, nip in the bud, from the source control SDH equipment quality. At the same time, through the experimental platform is set up to simulate test but also conducive to discover equipment failure causes; propose improvement of equipment manufacturers, protection of optical communication equipment to meet the power communication system design and construction requirements.But with a telecommunications network requirements are different, power system communication network has its own particularity, so the optical transmission system evaluation, needs the combination of power communication system of service needs, targeted test standard study, develop SDH test technical specification, this paper made analysis of optical transmission network capacity business needs, the SDH equipment main parameters, construction of network simulation, simulation operation, to determine the SDH certification testing process, testing method, testing standard, ensure power communication equipment system evaluation center into full play, to Guangdong power grid company communication system application needs to provide technical support. SDH of the evaluation system of formation can not only find communication equipment in the presence of various cannot verify the recessive problems, to the communication network in the network simulation, and can be more closely follow the modern communication technology development trend, for the study and formulation of electric power communication network development direction to provide technical basis for theory and practice.
