19、ion (This introduction is not part of IEEE 1115-2000, IEEE Recommended Practice for Sizing Nickel-Cadmium Batteries for Stationary Applications.) The storage battery is of primary importance in ensuring the satisfactory operation of generating stations, substations, and other stationary applications
20、. This recommended practice is based on commonly accepted methods used to defi ne the load and to ensure adequate battery capacity. The method described is applicable to all installations and battery sizes. The installations considered herein are designed for operation with a battery charger serving
21、 to maintain the battery in a charged condition as well as to supply the normal dc load. Alternate energy systems (e.g., wind- mills and photovoltaic systems) may provide only partial or intermittent charging, and are beyond the scope of this document. See IEEE Std 1144-1996 B6 1 for details. This r
22、ecommended practice was prepared by the Nickel-Cadmium Sizing Working Group of IEEE Standards Coordinating Committee 29 (SCC29). It may be used separately, but when combined with IEEE Std 1106-1995, it will provide the user with a general guide to designing, placing in service, and maintaining a nic

McDowall, Chair The following persons were on the balloting committee: When the IEEE-SA Standards Board approved this standard on 30 March 2000,

35、ibes methods for defi ning the dc load and for sizing a nickel-cadmium battery to supply that load. Some factors relating to cell selection are provided for consideration. 1.1 Scope This recommended practice covers the sizing of nickel-cadmium batteries used in full fl oat operation for stationary a
36、pplications. Installation, maintenance, qualifi cation, testing procedures, and consideration of battery types other than nickel-cadmium batteries are beyond the scope of this recommended practice. Design of the dc system and sizing of the battery charger(s) are also beyond the scope of this recomme
37、nded practice. 1.2 Purpose The purpose of this recommended practice is to provide a proven and standardized sizing technique for nickel-cadmium batteries. This sizing method takes normal usage factors into account, and forms the basis for reliable battery operation. 2. References This standard shall
38、 be used in conjunction with the following publications: IEEE Std 1106-1995, IEEE Recommended Practice for Installation, Maintenance, Testing, and Replacement of Vented Nickel-Cadmium Batteries for Stationary Applications. 1 IEEE Std 1184-1994, IEEE Guide for the Selection and Sizing of Batteries fo

41、nitions The following defi nitions apply specifi cally to this recommended practice. For terms not defi ned in this clause, please refer to the documents listed in Clause 2. 2 3.1 available capacity: The capacity for a given discharge time and end-of-discharge voltage that can be withdrawn from a ce
42、ll under the specifi c conditions of operation. 3.2 battery duty cycle: The loads a battery is expected to supply for specifi ed time periods. 3.3 full fl oat (constant potential) operation: Operation of a dc system with the battery, battery charger, and load all connected in parallel and with the b
43、attery charger supplying the normal dc load plus any self- discharge or charging current required by the battery. (The battery will deliver current only when the load exceeds the charger output.) 3.4 period: An interval of time in the battery duty cycle during which the load is assumed to be constan
44、t for purposes of cell sizing calculations. 3.5 rated capacity (nickel-cadmium cell): The capacity assigned to a nickel-cadmium cell by its manufac- turer for a specifi c constant current discharge, with a given discharge time, at a specifi ed electrolyte temperature, to a given end-of-discharge vol
45、tage. The conditions used to establish rated capacity are based on a constant current charge, in accordance with IEC 60623 (1990-03) B2 3 . 4. Defi ning loads 4.1 General considerations The duty cycle imposed on the battery by any of the conditions described here will depend on the dc system design
46、and the requirements of the installation. The battery must supply the dc power requirement when the following conditions occur: a)The load on the dc system exceeds the maximum output of the battery charger. b)The output of the battery charger is interrupted. c)The ac power is lost may result in a gr
47、eater dc power demand than in item b) above. The most severe of these conditions, in terms of battery load and duration, should be used to determine the battery size for the installation. 4.2 Load classifi cations The individual dc loads supplied by the battery during the duty cycle may be classifi
48、ed as continuous or noncontinuous. 4.2.1 Continuous loads Continuous loads are energized throughout the duty cycle. These loads are those normally carried by the battery charger and those initiated at the inception of the duty cycle. Typical continuous loads are 2 Information on references can be found in Clause 2. 3 The numbers in brackets correspond to those of the bibliography in Annex D.
