The following is the standard design of substation battery banks being purchased: The substation battery banks are sized and purchased by the substation engineering activity. Battery banks are purchased direct from pre-approved battery bank manufacturers.
Today, normal DC auxiliary supply systems in power substation are operating on the 110 V or 220 V level. Battery, charger and distribution switchboard are
Many references for stationary battery sys-tem design address only a specific battery technology, making it difficult to compare different types of batteries for their overall suitability to substation application. Also, most references do not address the particular requirements of the electrical substation environment and duty cycle.
A power substation can have one or several DC systems. Factors affecting the number of systems are the need for more than one voltage level and the need for duplicating systems. Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist.
The transmission portion of the substation uses dual PCM devices, and the distribution portion of the sub-station uses single PCM devices. The dc system is monitored via SCADA and mainte-nance and operations practices dictate that a charger malfunction must be corrected within eight hours or the substation must be taken out of service.
A-1 shows a single line diagram of a relatively large transmission and distribution substation that we will use as an example for performing the battery sizing calculations. The following assumptions have been made: The substation will have a dual battery system.
