         Abstract This article describes the optimization design of 11 kV distribution system，self - provided diesel generator power supply system and these two types of systems for Centaurus Project in Pakistan. Based on domestic and international codes and standards，and in combination with the project characteristics such as the load property and power capacity，the original foreign power supply scheme is optimized，meeting the requirements of relevant standards and significantly reducing the investment costs of the constructor’s side.
