Power system planning, design and operation of the fundamental task of national economic development plans in co-ordination arrangements, reasonable development and utilization of power resources, with less investment and operating costs, to meet the needs of the people of the national economy and livelihood of the departments growing required to provide adequate, reliable and quality power. Power systems including power generation, power transmission, transformation, distribution, consumption and the corresponding communications, security, automatic devices, relay protection, automation facilities such as scheduling. A large number of facts at home and abroad show that a reliable supply of electricity, economic and quality of electric power system depends not only on a variety of equipment performance and quality, but also depends on the power system planning, design and operational management. Power system planning is based on national economic development plans and the development of the existing power system to the specific program, in power system design, and implement principles and policies of the country, in accordance with the technical requirements for the design; starting from a whole, in-depth demonstration of the power distribution reasonableness of the proposed network design, and demonstrate the relia
