Substation Auxiliary Power Supplies
Transmission and Distribution Electrical Engineering, 2012Co-Authors: C.r. Bayliss, B.j. HardyAbstract:AC power is required for Substation Building small power, lighting, heating and ventilation, some communications equipment, switchgear operating mechanisms, anticondensation heaters, and motors. DC power is used to feed essential services such as circuit breaker trip coils and associated relays, supervisory control and data acquisition, and communications equipment. This chapter describes how these auxiliary supplies are derived and explains how to specify such equipment. Capital cost and reliability objectives must first be considered before defining the battery and battery charger combination to be used for a specific installation. Charger units are used to supply either just a battery to provide an autonomous DC supply or a battery/inverter combination to provide an autonomous AC supply. The level of “autonomy” is usually defined in terms of the number of hours or minutes the equipment will enable a specified load to function correctly after loss of input mains AC supply. The capacity of the charger must also be such that after a severe discharge it has the capacity to supply the full DC system load current and the full charging current simultaneously.

Substation Building Services
Transmission and Distribution Electrical Engineering, 2011Co-Authors: C.r. Bayliss, B.j. HardyAbstract:Publisher Summary This chapter introduces some of the main principles involved with Substation control Building and switchyard services. Such work is often left to specialist Building services, engineering groups, and architects. It covers basic internal and external lighting design, heating, ventilation, and airconditioning (HVAC) practice, and the different types of low voltage distribution systems in sufficient detail as likely to be encountered by the power engineer. Light consists of electromagnetic radiation with wavelengths between 760 and 380 nm to which the eye is sensitive. This energy spectrum (red, orange, yellow, yellow-green, green, green-blue, blue, and violet) lies between the infrared (7002,000 nm) and the ultraviolet (200400 nm) wavelength ranges. Emergency lighting involves battery backup derived either from cells within the fittings or from the main Substation DC supply. The units are designed to have a given “autonomy” such that upon AC failure the lighting continues to operate for a specified number of hours from the battery source.
