Commissioning

The standard specifies marking, designation, dimensions, tests and requirements for large format lithium-ion secondary single cells and batteries used in Industrial Applications including Stationary applications.

The standard covers electrical, dimensional, and mechanical characteristics, taking into consideration certain safety features, for current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control of equipment associated with the generation, transmission, and distribution of alternating current. The aim is to provide a basis for performance, interchangeability, and safety of equipment covered and to assist in the proper selection of such equipment. Accuracy classes for metering service are provided.

The guide was written to provide a relevant PV battery test procedure that can be used to evaluate battery performance and identify appropriate PV battery charging requirements. The document contains a tutorial on Lead-Acid battery technology, battery charging characteristics, and a laboratory test procedure to evaluate charge parameters and battery performance.

The document provides a 3-level system of VRLA String Safety and Performance Criteria based on Telcordia generic requirements documents. The VRLA string criteria levels are defined as follows: ? Level 1, Safety and Minimal Operability – minimum acceptable level of compliance needed to preclude hazards and degradation of the network facility and hazards to personnel, and needed to ensure battery operability at the installation time in controlled environments.

1.1 These requirements cover inverters, converters, charge controllers, and interconnection system equipment (ISE) intended for use in stand-alone (not grid-connected) or utility-interactive (grid-connected) power systems. 1.2 For utility-interactive equipment, these requirements are intended to supplement and be used in conjunction with the Standard for Interconnecting Distributed Resources With Electric Power Systems, IEEE 1547, and the Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547.1.

IEC 61427-2:2015 relates to secondary batteries used in on-grid Electrical Energy Storage (EES) applications and provides the associated methods of test for the verification of their endurance, properties and electrical performance in such applications. The test methods are essentially battery chemistry neutral, i.e. applicable to all secondary battery types.

A.1.1 The following is a suggested procedure for determining the Code requirements for a building or structure: (1) Determine the occupancy classification by referring to the occupancy definitions in Chapter 6 and the occupancy Chapters 12 through 42. (See 6.1.14 for buildings withmore than one use.) (2) Determine if the building or structure is new or existing. (See the definitions in Chapter 3.) (3) Determine the occupant load. (See 7.3.1.) (4) Determine the hazard of contents. (See Section 6.2.) (5) Refer to the applicable occupancy chapter of the Code, Chapters 12 through 42.

1.1 These requirements cover instrument batteries, enclosed batteries, emergency lighting and power batteries and uninterruptible power supply batteries of the valve regulated or vented type. A battery system composed of vented or valve regulated types with battery management controls and other battery system components, and other chemistries or battery types are covered by the Standard for Batteries for Use in Light Electric Rail (LER) Applications and Stationary Applications, UL 1973.

This standard specifies the type, production, and commissioning tests that shall be performed to demonstrate that the interconnection functions and equipment of a distributed resource (DR) conform to IEEE Standard P1547; Interconnection equipment that connects distributed resources (DR) to an electric power system (EPS) must meet the requirements specified in IEEE Standard P1547. Standardized test procedures are necessary to establish and verify compliance with those requirements.
