1.0.1 This code is formulated with a view to normalizing substation design and enabling such design to meeting the national relevant policies, laws and regulations, and to achieve safety and reliability, economy and rationality requirements.
1.0.2 This code is applicable to the substation design of construction, expansion and renovation works with voltage 35kV~110kV and single transformer capacity 5000kV•A or above.
1.0.3 The substation design shall be based on 5~10 years' development plan of the works and achieve the combination of long and short term, give priority to short term, correctly handle the relation between short-term construction and long-term development, and reserve the expansion possibility as required.
1.0.4 The substation design shall depart from overall situation, give overall consideration and reasonably determine the design scheme according to load nature, power capacity, environment characteristics and in combination with local development level.
1.0.5 The substation design shall persist in the principle of resource saving and social benefit compromise.
1.0.6 The substation design shall not only comply with the requirements of this code, but also those in the current relevant standards of the nation.
