In this paper, based on the control and protection requirements for urban distribution network, after analysis of the existing protection system deficiencies, wide area control and protection technique is applied to urban distribution network, thus improving the reliability of power supply. Based on the smart substation technique, the system architecture and performance characteristics of wide area control and protection system for distribution network is introduced first, and then coordination mechanism between wide area con-trol and protection is established. Finally, Shenzhen Qianhai 20kV distribution network is taken as an example to evaluate the perform-ance of wide area control and protection system via simulation. The generalization capability of wide area control and protection for different distribution networks is also analyzed.
