Scope

GB/T 39674-2020 is the English-translated version of 电力软交换系统测试规范.

GB/T 39674-2020 specifies test methods and requirements for the power softswitch system, covering its functions, performance, interoperability protocol consistency, service quality, reliability and environmental adaptability.

Clause 1 states that the standard applies to the type test, interconnection verification, factory inspection and engineering acceptance of power softswitch equipment.

After Scope, Normative references, Terms and definitions and Abbreviations, the test clauses run in sequence: basic function test of the power softswitch system, power dispatch soft switch function test, interworking protocol conformance test, system performance test, service quality test, reliability test and environmental adaptability test, the dispatch function test and the protocol conformance test filling most of the page count.

Clause 2 cites GB/T 2423.1, GB/T 2423.2, GB/T 2423.3, GB/T 9254, GB/T 17626.2, GB/T 17626.3, GB/T 17626.4, GB/T 17626.5, GB/T 17626.18 and GB/T 31998-2015, together with the test-method standards YD/T 1387.1, YD/T 1387.3, YD/T 1389, YD/T 1408, YD/T 1435, YD/T 1517, YD/T 1911 and YD/T 2033.3.

Clause 3 states that the terms and definitions of GB/T 31998-2015 apply and prints one of its own, the dual-mode dispatch terminal, which can work in circuit and packet switching modes at the same time, is connected to the dispatching program control switch through a digital interface and registers to the packet dispatching and switching platform through the IP network interface.

The foreword records that the standard was proposed by the China Electricity Council and is under the jurisdiction of the National Power System Management and Information Exchange Standardization Technical Committee (SAC/TC82). It was issued on 14 December 2020 and has applied since 1 July 2021.
