Foreword
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 34120-2017 "Technical Specifications for Energy Storage Converters for Electrochemical Energy Storage Systems" and is consistent with GB/T 34120-2017:
In addition to structural adjustments and editorial changes, the main technical changes are as follows:
---Changed the scope of use of the document and determined the upper limit of "output AC voltage" to 35kV (see Chapter 1,:2017 Edition No: 1
chapter);
---Added "AC port", "DC port", "fault ride through", "low voltage ride through", "high voltage ride through", "primary frequency modulation" and "inertia response"
and "contact current" and other terms, deleted terms that are repeated with DL/T 2528 (see Chapter 3, Chapter 3 of the:2017 edition);
---Added "by connection relationship with the power grid", "by access voltage level", "by installation and use environment", "by cooling method" and "by topology structure"
Product classifications such as “structure” and “product coding” (see Chapter 4);
---Changed the "electrical conditions for grid-connected operation" and added "off-grid operation conditions" (see 5:2 and 5:3, 5:1 of the:2017 version);
---Added "Appearance and Protection Level" (see Chapter 6);
---Added "start and stop", "alarm and protection", "insulation resistance detection", "operation information monitoring", "statistics" and "data display and storage", etc:
Functional requirements (see 7:1, 7:4, 7:5, 7:7, 7:8 and 7:9);

Electrical performance requirements such as "equipment availability" (see 8:1:1:1, 8:1:1:3, 8:1:1:4, 8:1:8:1:2, 8:1:8:4, 8:1:9 and 8:1:14);
---The "electrical safety distance" and "insulation requirements" have been changed, and "equipotential connection and protective grounding" and "capacitor residual energy hazard prevention" have been added:
Safety performance requirements such as "protection" and "mechanical protection" (see 8:2:1:1, 8:2:1:2, 8:2:1:3, 8:2:1:4, 8:2:4, 5:7 of the:2017 edition
and 5:8);
---The requirements for "low temperature adaptability", "high temperature adaptability" and "humid heat adaptability" have been changed, and the requirements for "salt spray adaptability" have been added (see
8:2:3:1~8:2:3:4,:2017 version 5:4:20);
---Changed the "electromagnetic compatibility" requirements and put forward corresponding requirements according to different access voltage levels (see Chapter 9, 5:8 of the:2017 edition);
---Added "auxiliary system" (see Chapter 10);
---The requirements for "inspection rules" have been changed, and test items have been adjusted according to product classification and new technical requirements (see Chapter 11,:2017
