As an important means to ensure the safe operation of the electrical equipments as well as to enhance the level of substation equipment production and operation management, the substation equipment condition monitoring system has become a hot spot of smart grid research. Taking the smart substation condition monitoring system as a research ground, this paper proposes a construction scheme for smart substation condition monitoring system based on wireless sensors networks, which enables wireless communication among several levels. And then this paper discusses system architecture, interlace specification, solar power system, IEC 61850 based wireless communication technology and wireless communication module configuration problem, And the program is applied to smart substation condition monitoring system, through run the system. Practical application results show that the scheme can reduce the overall cost of construction and improve system performance of the substation condition rnonitoring system, and has a very important significance for the construction of the substation equipment condition monitoring system.
