IEC TR 61850-90-7:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed…

IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter. The functions defined in this document…

IEC TR 61850-90-27:2023, which is a Technical Report, is to provide basic aspects that need to be considered when using IEC 61850 for information exchange between systems and components to support applications for thermal systems connected to electric power networks. Thermal systems isolated from electric power networks are outside the scope of this document. From the perspective of category,…

IEC 63376:2023 specifies the functions and the information flows of industrial Facility Energy Management System (FEMS). Generic functions are defined for the FEMS, to enable upgrading traditional Energy Management System (EMS) from visualization of the status of energy consumption to automation of energy management defining a closer relation with other management and control systems. A generic…

This document provides the basis for organizational improvement underpinned by quality workforce data that supports analysis and evidenced-based decision-making. Workforce data quality, for the purpose of this document, is the process of: a)       workforce data determination; b)       data capture; c)        data maintenance; d)       data review processes. The focus of this document is on the…

This document —     introduces conditions, constraints and resources necessary to evaluate a measurement method or a result; —     defines an organizational scheme for the acquisition of trueness and precision data by study; —     provides the necessary definitions, statistical model and principles for ISO 5725 (all parts). —     is not applicable to proficiency testing or production of the…

This document provides users with a summary of the existing knowledge about ergonomics considerations for the influence of sound in use environments on humans. It describes how unwanted effects of sound (noise) can be controlled. The main goals for controlling the acoustic use environment are reducing the rating level of sound in general, optimizing signal-to-noise ratio and sound reduction…

IEC TS 62786-41:2023 (E), which is a Technical Specification, defines minimum requirements for frequency and rate of change of frequency measurements used to control distributed energy resources (DER) and loads connected to electrical power networks. This document specifies the characteristics of frequency and rate of change of frequency measurements to evaluate their performances. It describes…

This document extends ISO 24617-7:2020, which specifies ways of annotating spatial information in natural language such as English, by establishing a formal semantics for its abstract syntax. The task of the proposed semantics is of two kinds: a)       translation of annotation structures to semantic forms; b)       model-theoretic interpretation of semantic forms. Semantic forms are represented…

This document provides recommendations on how to measure learning. Since the selection of metrics depends on the reason to measure and the user of the metrics, and since a balanced set of metrics is important to avoid unintended consequences, the document begins with a framework for organizational learning and development (L&D), including five categories of users, four broad reasons to…
