For the most part, electric power substations are viewed as the most integral part of a power utilities’ electric system, with electric systems being comprised of power generation, transmission, and distribution systems. Below is a non-exhaustive list of commonly used technical standards on 110 kV and 220 kV Transmission connections for demand and generation customers to consider when developing their connection projects and associated planning applications. ANSI is also actively engaged in accrediting programs that assess conformance to standards – including globally recognized cross-sector programs such as the ISO 9000 (quality) and ISO 14000 (environmental) management systems. Engineering Standards which apply include IEEE standard AC Substation Grounding, IEEE standard Lead Acid Battery Sizing, and IEEE standard Lightning Protection. IEEE Standard 693, “Recommended Practice for the Seismic Design of Substations”, was established to have a consistent, comprehensive seismic design guideline utilities can specify to ensure equipment is not vulnerable to a design basis earthquake. The substation should be designed so that. 22 0 obj This allows purchasers to select a specific standard solution knowing that multiple vendors will be prepared to supply that standard, and that different vendor’s produces will be able to inter-operate with each other. In other words, at least 80% of substation projects can use predefined standardized designs while only 20% or fewer will require some form of customization. 2.
