  • Term
    Definition
  • Describes the testing requirements for photovoltaic modules in order to provide safe electrical and mechanical operation during their expected lifetime. Addresses the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses.
  • Specifies verification and validation procedures for the design of the control-room system of nuclear power plants and gives verification and validation criteria for the assignment of functions and for the integrated control-room system.
  • IEC 61772:2009 supplements IEC 60964 and presents design requirements for the application of VDUs in main control rooms of nuclear power plants. Assists the designer in specifying VDU applications including displays on individual workstations and larger displays for group-working or distant viewing.
  • Specifies a safety communication layer (services and protocol) based on CPF 18 of IEC 61784-2 and IEC 61158 Type 22. It identifies the principles for functional safety communications defined in IEC 61784-3 that are relevant for this safety communication layer.
  • Specifies requirements and makes recommendations for the design and development, integration and validation of PDS(SR)s in terms of their functional safety considerations.
  • Describes procedures for on-site measurement of crystalline silicon photovoltaic (PV) array characteristics and for extrapolating these data to Standard Test Conditions (STC) or other selected temperatures and irradiance values.
  • Specifies functional analysis and assignment procedures for the design of the control-room system for nuclear power plants and gives rules for developing criteria for the assignment of functions. Supplements IEC 60964. Is applicable to the design of new control-rooms or to backfits to existing(...)
  • Applies to substation automation systems and more specifically defines the communication between intelligent electronic devices in the substation and the related system requirements.
  • EC 61850-6:2009(E) specifies a file format for describing communication-related IED (Intelligent Electronic Device) configurations and IED parameters, communication system configurations, switch yard (function) structures, and the relations between them. The main purpose of this format is to(...)
  • EC 61850-7-2:2010(E) applies to the ACSI communication for utility automation. The ACSI provides the following abstract communication service interfaces: abstract interface describing communications between a client and a remote server; and abstract interface for fast and reliable system-wide(...)
  • IEC 61850-7-4:2010(E) specifies the information model of devices and functions generally related to common use regarding applications in systems for power utility automation. It also contains the information model of devices and function-related applications in substations. In particular, it(...)
  • “IEC 61851-23:2014, gives the requirements for d.c. electric vehicle (EV) charging stations, herein also referred to as “DC charger”, for conductive connection to the vehicle, with an a.c. or d.c. input voltage up to 1 000 V a.c. and up to 1 500 V d.c. according to IEC 60038. It provides the(...)
  • IEC 61851-24:2014, together with IEC 61851-23, applies to digital communication between a d.c. EV charging station and an electric road vehicle (EV) for control of d.c. charging, with an a.c. or d.c. input voltage up to 1 000 V a.c. and up to 1 500 V d.c. for the conductive charging procedure.
  • IEC 61853-1:2011 describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures. The object is to define a testing and rating system, which provides the PV module power (watts) at maximum power operation for a set of(...)
  • Provides a guide for HAZOP studies of systems utilizing the specific set of guide words defined in this standard. Also gives guidance on application of the technique and on the HAZOP study procedure, including definition, preparation, examination sessions and resulting documentation and follow-up.
  • Defines the requirements for assuring that automatic setpoints for nuclear safety system instrumentation are established and maintained within specified limits in nuclear power plants and nuclear reactor facilities.
  • Specifies the information content of a set of message types that can be used to support many of the business functions related to network operations. Typical uses of the message types defined in this part include data acquisition by external systems, fault isolation, fault restoration, trouble(...)
  • Specifies the information content of a set of message types that can be used to support many of the business functions related to records and asset management. Typical uses of the message types include network extension planning, copying feeder or other network data between systems, network or(...)
  • IEC 61968-13:2008(E) specifies the format and rules for exchanging modelling information based upon the Common Information Model ("CIM") and related to distribution network data. Allows the exchange of instance data in bulk. Thus, the imported network model data should be sufficient to allow(...)
  • Provides a set of guidelines and general infrastructure capabilities required for the application of the EMS-API interface standards. Describes typical integration scenarios where these standards are to be applied and the types of applications to be integrated. Defines a reference model and(...)
