These requirements cover bidirectional electric vehicle charging equipment that charge electric vehicles from an electric power system and also include functionality to export power from the electric vehicle to an electric power system. When commanded, the bidirectional charging equipment exports electric power from the electric vehicle stored energy supply to the electric power system (EPS) to supply power to common loads.
Third parties must use certified equipment (both behind the meter and on the distribution grid) when attempting to interconnect new components to the grid. Certified equipment is equipment that has passed through rigorous certification testing procedures done by Nationally Recognized Testing Laboratories (NRTLs); UL is one such example. NRTLs create testing procedures for equipment that verify equipment functionality and safety to pre-set testing standards created by nationally recognized engineering groups such as IEEE.
1.1 These requirements cover Wind Turbine Converter (WTC) products and assemblies. Some of the features and functions of these products include but are not limited to, generation of real and reactive power in parallel with the electric power system, EPS (electric utility grid), supplying power in a standalone operational mode, multiple mode operation, and bidirectional power flow operation with the EPS.
These requirements cover ESS that are intended to store energy from power or other sources and provide electrical or other types of energy to loads or power conversion equipment. The ESS may include equipment for charging, discharging, control, protection, communication, controlling the system environment, fuel or other fluid movement and containment, etc. The system may contain other ancillary equipment related to the functioning of the energy storage system.
The document is intended to assist code authorities, designers, and installers to develop, and install a complete lightning protection system that can withstand the tremendous power of a lightning strike. Depending on the type, a strike can exceed 300,000 Amperes, over one gigavolt (one billion volts) and with temperatures as high as 36,000 Deg. F., or about three times as hot as the surface of the sun. This guide does not include information on protection of equipment inside a building.
The document presents general requirements that Telcordia and participating industry representatives view as applicable to large format non-aqueous rechargeable lithium batteries to replace or interoperate with conventional batteries (i.e., Lead-Acid, nickel-based); function seamlessly with DC power plants; and provide reliable backup power to load equipment in a network environment of a typical telecommunications service provider.
The document provides a 3-level system of VRLA String Safety and Performance Criteria based on Telcordia generic requirements documents. The VRLA string criteria levels are defined as follows: ? Level 1, Safety and Minimal Operability – minimum acceptable level of compliance needed to preclude hazards and degradation of the network facility and hazards to personnel, and needed to ensure battery operability at the installation time in controlled environments.
The technical requirements for parallel generation are in place to ensure public and employee safety, protect the integrity of Toronto Hydro’s system, and guarantee reliable and quality service to Toronto Hydro customers. The technical requirements in this document are for the protection of Toronto Hydro's facilities, and the Generator should satisfy itself as to any requirements for the protection of its own facilities.
