Technical rule for distributed resources connected to distribution network ICS 27.160 F12 Record number. 43499-2014 Energy Industry Standard of the People 's Republic of China Technical specification for distributed power supply distribution networks 2013-11-28 release 2014-04-01 implementation National Energy Board released

1 Scope

This standard specifies the general principles and technical requirements for distributed power supply access to the grid. This standard applies to 30kV and below the voltage level access to the new grid, alteration and expansion of distributed power supply.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. This is the latest version of the book, including all modifications. GB 2894 Safety signs and guidelines for their use

3 terms and definitions

The following terms and definitions apply to this document. 3.1 Distributed power Access 35kV and below the voltage level, located near the user, local consumption-based power, including synchronous generators, asynchronous generators, Converter and other types. 3.2 Converter An electrical device for converting electrical power into electrical power for one or more forms suitable for use by a grid or a user. Including rectifiers, Inverters, AC converters and DC converters. 3.3 Converter type power supply converter-type power supply All or part of the power supply connected to the grid through the converter. Synchronous generator type power supply Asynchronous left motor type power supply Through the asynchronous generator directly connected to the power grid. Point of interconnection For a distributed power supply with a booster station, it refers to the high voltage side bus or node of the booster station. For distributed power supplies without booster stations, refer to distributed Power output summary point. The definition of the dotted network can be found in Appendix A of this standard. Public connection point of common coupling User access to the public grid connection. Island islanding Including the load and power of some of the grid, from the main network after the separation from the state to continue to run alone. Isolated islands can be divided into unplanned islands and planned islands. Note. Unplanned islands are unscheduled and unregulated. Planned islands are planned to occur in a planned control strategy.
