In view of the reliability and the efficiency of the remote control systems for Electric Power Equipment, a remote control system is proposed in which the control information interacts by low voltage power network communication. Low voltage power network is used as the channel for control information of Electric Power Equipment. The MSK modulation and demodulation technology that is seasoned with the channel characteristics of low voltage power network were selected, while the theory of MSK is analyzed，and the remote control system model to Electric Power Equipment based on low voltage power network communication with MSK and Programmable Logic Controller is constructed. The remote control system for Electric Power Equipment is manufactured based on the model. Theoretical analysis and experimental results show that MSK can satisfy the channel characteristics of low voltage power network, realize reliable transmission of the remote control signals, and improve the reliability of the remote control system while decrease the cost.
