With the continuous expansion of the grid size, the number of checkpoints metering device is also increased workload and difficulty inspectors also increasing, to carry out verification and monitoring of remote metering devices mark significant. Discusses the remote calibration and monitoring system principle, function and application metering device at checkpoints, and also describes the configuration and functions of the system back-office support software, scientifically demonstrated the remote meter error, PT secondary circuit drop, CT and secondary circuit admittance verification and monitoring of significance.

This paper describes the design of a CAN bus network industrial data acquisition and control system based on the application layer protocol, the CANO pen protocol. The structure of the control system is for the distributed control system. In this paper, it discuss the network for data acquisition and control system, Ethernet access control system, and provides convenience for remote control and data acquisition and processing. The software part of this design is the real-time operating system, which make the system more secure, efficient operation.

The distribution network communication technology plays a very important role in the distribution network automation. The intelligent level of distribution network is largely affected by the application of distribution network communication technology. This paper summarizes the EPON intelligent network communication technology, puts forward the related problems of EPON intelligent network communication application, and analysis of EPON intelligent network communication application conditions based on this.

With the improvement of power industry modernization, electric power communication service object is no longer confined to the electric power dispatching, and the scope of services business also won the development, which requires the power system communication network is stable, reliable and efficient. The reliability of the power system optical fiber transmission network operation is an important guarantee of electric power system`s production safety and efficiency. In order to facilitate the planning and design of optical fiber transmission network management and maintenance, this paper proposed an optimization strategy based on the analysis and research of electric power communication optical fiber transmission network evaluation methods.

Recently, with the quickly growing in power industry of our country, the power supply enterprise also pay more attention to communication security. Concerning the running time of communication network of power supply enterprise, there must be a communication platform for control support. In the new period, many intelligent devices enter the power industry, what affecting the system stability and security. This paper mainly studies on the safety of power supply enterprise communications technical support and application, analysis of security problems, and puts forward the solving measures.
