This part of IEC 61400 defines and specifies the quantities that are determined to characterize the electrical characteristics of grid-connected power plants (PPs).

This document defines the measurement and test procedures for quantifying the electrical characteristics as basis for the verification of compliance of PPs, including:
• power quality aspects,
• steady state operation,
• dynamic response (undervoltage and overvoltage fault ride-through),
• disconnection from grid (grid protection),
• control performance.

This document defines a uniform functionality test and measurement procedure for the power plant controller (PPC), as a basis for the unit test of the power plant controller.

This document defines the procedures for assessing compliance with electrical connection requirements, including the aggregation methods for power quality aspects such as voltage variations, flicker, harmonics and interharmonics.

This document defines the procedures for measurement and fault recording, for example for the verification of power plant electrical simulation models in relation to undervoltage and overvoltage ride-through events.

These measurement procedures are valid for power plants, including the power plant controller and other connected equipment, necessary for the operation of the power plant. The measurement procedures are valid for any size of power plant connected to the point of connection (POC) at one connection point.

The procedures for assessing and verifying the compliance with grid connection requirements are valid for power plants in power systems with fixed frequency and a sufficient short-circuit power.

Out of the scope of this document are:
– evaluation of several power plants, i.e. the control by a cluster management of several power plants (PPs) or evaluation where the power plant is connected to several connection points;
– compliance test and performance requirements, including pass or fail criteria;
– specific component test and validation of the PP equipment (switchgear, cables, transformers, etc.), which are covered by other IEC standards;
– wind power plant model validation, as defined in IEC 61400-27-2;
– load flow calculation methods and load flow study guidelines;
– test and measurement of the communication interface and system of the PP as defined in the IEC 61400-25 series.

NOTE For the purposes of this document, the following terms for system voltage apply, based on IEC 60038:
– low voltage (LV) refers to 100 V < Un ≤ 1 kV;
– medium voltage (MV) refers to 1 kV < Un ≤ 35 kV;
– high voltage (HV) refers to 35 kV < Un ≤ 230 kV;
– extra high voltage (EHV) refers to Un > 230 kV.

The Fieldbus Application Layer (FAL) provides user programs with a means to access the fieldbus communication environment. In this respect, the FAL can be considered as a window between corresponding application programs.

This part of IEC 61158 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 28 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window can cause failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life.

This document defines in an abstract way the externally visible behavior provided by the Type 28 of the fieldbus Application Layer in terms of:
• the abstract syntax defining the application layer protocol data units conveyed between communicating application entities,
• the transfer syntax defining the application layer protocol data units conveyed between communicating application entities,
• the application context state machine defining the application service behavior visible between communicating application entities; and
• the application relationship state machines defining the communication behavior visible between communicating application entities.

The purpose of this document is to define the protocol provided to:
• the wire-representation of the service primitives defined in IEC 61158-5-28, and
• the externally visible behavior associated with their transfer.

This document specifies the protocol of the Type 28 IEC fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI Application Layer Structure (ISO/IEC 9545).
