In order to avoid the operation accidents of power system caused by the influences of various artificial or nature factors, the paper explored the early warning of characteristic parameters on power system based on embedded system. In the paper, it taken a 110kV substation as an example, studied on therelated algorithm of the electric characteristic parameters, constructed the hardware and software platformbased on embedded microprocessor, and designed the hardware circuit and software control program. The commissioning test demonstrated that it could accurately judge the latent fault of related devices, and send correctly the trip command to make the isolation between the fault device and the power system so as to protect the system from being damaged. The experiment results show that it is effective and available to early warning of power system.

To improve the objectivity and accuracy of evaluation for electromagnetic environment complexity and its influence on communication equipment, a subjective complexity evaluation method of electromagnetic environment oriented to the communication equipment is presented based on sensitivity and RF protection ratio of communication equipment. Based on statistical concept, the energy correlation factor is modified, and modulation and polarization correlation concept are imported into this method, by which the factor of energy correlation is modified and the subjective evaluation is made by analyzing the time domain correlation, frequency domain correlation, energy domain correlation, modulation correlation and polarization correlation of the electromagnetic environment. These simulation results indicate that communication equipment with various working parameters are influenced differently under the same electromagnetic environment. Namely, the complexities of electromagnetic environment for communication equipment with various working parameters are different.

Hardware-in-the-loop communication equipment simulation is an important step of the development about communications and electromagnetic environment simulation. Reference to the "software radio" design thinking, the source library is generated by the software and different communication signals are generated by the fixed hardware frame. The system achieves “versatility”. GMSK in wireless communications has been widely applied. It is one of the important signals generated by the simulator. Based on analysis of the structure, the paper introduces the design of the simulator. It also provides the software simulation of Matlab. It provides a reference simulation for communications equipment and electromagnetic environment simulation.

Currently, the evaluation methods of importance measures such as structure importance measure, criticality reliability importance and B-reliability importance, have some shortcomings that the evaluation results are not comprehensive enough and the scope of usage. In order to accurately evaluate the importance measures of equipment, and to reflect the impact of the equipment on the communication network, a comprehensive evaluation method of importance measure is put forward. According to the influence of inherent structure of system and service reliability, the importance measure of equipment is calculated. By the coefficient modification, it can accurately evaluate comprehensive evaluation of electric power communication equipment based on reliability importance measures. Example result verifies the feasibility and validity of the comprehensive evaluation method.

Communication Access Network of Electric Power System is the key of Communications Network for Smart Grid. There are kinds of access technologies of Telecommunications for Electric Power System. However there is not a unified software platform for electric power communication access devices based on these technologies. So it cannot be adapt to the rapid development of electric power communication equipment, communication test, flexible configuration, and also cannot be quickly adapt to changes in the electric power communication needs. This paper introduces Reconfigurable Switch Software Platform (RSSP) s design, analyzes the architecture of RSSP in detail. As an example, this paper also proposes an implementation scheme of OLT based on RSSP.
