Smart micro-grid protection equipment technical guidance

1 Scope

GB/Z 34161-2017 is the Chinese national standard on technical guide for smart protection equipment of microgrid, in the field of electrical engineering. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 7 September 2017 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. Classification: ICS 29.240.01, CCS K45. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Guidance Technical Document specifies the general requirements for intelligent micro-grid protection equipment, technical requirements, protection configuration, test methods and other requirements. This Guidance Document is applicable to grid-connected and independent power supply AC micro-grids that are connected to 35kV and below voltage distribution networks Grid system, as a product design, manufacture, inspection and operation of the basis.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Microgrid By the distributed generation, electricity load, monitoring, protection and automation devices (including energy storage if necessary), is a can be achieved within the basic Ministry of power supply balance of small power supply network. Micro-grid into grid-based micro-grid and independent micro-grid. Note that grid-connected microgrid refers to the microgrid connected to the grid, which can run both in grid and grid, and can operate independently from the grid. Independent micro-grid refers to not big Grid-connected microgrids can independently guarantee the stability of power generation and supply in the microgrid. Generally, they refer to outlying areas where conventional power grids can not radiate.
