Basic Information
Scope
1.0.1 In order to improve the comprehensive energy utilization efficiency of natural gas, build safe and efficient natural gas distributed energy stations, and standardize the design of natural gas distributed energy stations, these regulations are formulated. 1.0.2 These regulations apply to the design of new or expanded, modified building-type and regional-type natural gas distributed energy stations. 1.0.3 These regulations apply to the following prime mover capacities: 1. Gas turbine generator sets with a single-unit capacity not exceeding 50 MW; 2. Gas internal combustion engine generator sets with a single-unit capacity not exceeding 10 MW. 1.0.4 These regulations apply to the following project scopes: 1. Natural gas distributed energy stations; 2. Natural gas supply systems; 3. External cooling and heating pipe networks; 4. Facilities for grid connection; 5. Water supply and wastewater discharge systems. 1.0.5 Natural gas distributed energy stations shall follow the principle of self-generation and self-use of electricity and maximize the utilization of waste heat. The equipment configuration and operating mode of the system shall be determined after a technical and economic comparison. 1.0.6 In addition to complying with the provisions of these regulations, the design of natural gas distributed energy stations shall also comply with the provisions of current national standards and relevant industry standards.
