Performance

Control architecture for high-power electronics from power semiconductor device levels to the power system level is defined and characterized. Coverage includes the application of power electronics in the areas of Power Quality/Custom Power, Flexible AC Transmission Systems (FACTS), High Voltage DC Transmission (HVDC), Distributed Generation, Energy Storage applications, etc. with a power range from hundreds of kW to thousands of MW, but with emphasis on the 1 MW to hundreds of MW.

A method for defining the electrical load supplied by a nickel-cadmium battery and for sizing the battery to supply that load is described in this recommended practice.

Description: Considered in this guide are the components of both the ac and dc systems and the provided guidelines and recommendations for designing the appropriate systems for the substation under consideration. This guide includes the low-voltage auxiliary systems from the source(s) to the distribution point(s). Reliability requirements and load characteristics are discussed and distribution methods are recommended.

1.1

This Standard applies to exit signs, unit equipment, emergency luminaires, and central power systems intended for connection to circuits with nominal voltages of 600 V and less and providing illumination in the event of a failure of the normal power supply for nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I.



1.2

This Standard includes requirements for the construction of emergency lighting equipment to preclude fire and shock hazards and to ensure that the equipment has the minimum capability for performing its intended function.



1.3

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard.



Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.



Notes to tables and figures are considered part of the table or figure and may be written as requirements.



Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.



1.4

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

Preface:
This is the third edition of CSA C381.2, Energy performance of battery-charging systems and uninterruptible power supplies. It supersedes the previous editions published in 2014 and 2008 under the title, Test method for determining the energy efficiency of battery-charging systems.
This Standard specifies requirements, definitions, and test methods for determining the energy performance of battery-charging systems.
Scope:

This part of the IEC 61427 series gives general information relating to the requirements for the secondary batteries used in photovoltaic energy systems (PVES) and to the typical methods of test used for the verification of battery performances. This part deals with cells and batteries used in photovoltaic off-grid applications.
NOTE The part 2 of this series will cover cells and batteries used in "renewable energy storage in on-grid applications".

This part of IEC 60896 is applicable to lead-acid cells and batteries which are designed for service in fixed locations (i.e. not habitually to be moved from place to place) and which are permanently connected to the load and to the d.c. power supply. Batteries operating in such applications are called "stationary batteries".



Any type or construction of lead-acid battery may be used for stationary battery applications. This part 11 of the standard is applicable to vented types only.



The object of this standard is to specify general requirements and the main characteristics, together with corresponding test methods associated with all types and construction modes of lead-acid stationary batteries, excluding valve-regulated types.



Recommendations on the use of tests for stationary battery application are given in Table A.1.



Recommendations relating the type of cell or monobloc to the use of tests are given in Table A.2.



Statements and claims of basic performance data by the manufacturer shall correspond to those tests.



The tests may also be used for type qualification. 

This part of IEC 60896 applies to all stationary lead-acid cells and monobloc batteries of the valve regulated type for float charge applications, (i.e. permanently connected to a load and to a d.c. power supply), in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS), utility switching, emergency power or similar applications.

Abstract: Part 2 sets out recommended practices for the installation, maintenance, testing and replacement of sealed secondary batteries permanently installed in buildings.
