In this paper, a self powered circuit with composite energy storage for monitoring terminal in distribution network is proposed, which is consist of a rectifier circuit, DC/DC converter and composite energy storage. Firstly, the self powered circuit obtained energy by CT (Current Transformer) from the lines in distribution network. Then, the expected DC voltage was obtained by rectifier circuit and regulated by DC/DC converter. To enhance the power supply reliability, composite energy storage is applied, which is regulated by coordinated control. To verify the effectiveness, a simulation model was built in MATLAB, and the result are satisfactory.
