This part of IEC 61400 defines standard electrical simulation models for wind turbines and wind
power plants. The specified models are time domain positive sequence simulation models,
intended to be used in power system and grid stability analyses. The models are applicable for
dynamic simulations of short term stability in power systems.
This document defines the generic terms and parameters for the electrical simulation models.
This document specifies electrical simulation models for the generic wind power plant
topologies / configurations currently on the market. The wind power plant models include wind
turbines, wind power plant control and auxiliary equipment. The wind power plant models are
described in a modular way which can be applied for future wind power plant concepts and with
different wind turbine concepts.
This document specifies electrical simulation models for the generic wind turbine
topologies/concepts/configurations currently on the market. The purpose of the models is to
specify the electrical characteristics of a wind turbine at the wind turbine terminals. The wind
turbine models are described in a modular way which can be applied for future wind turbine
concepts. The specified wind turbine models can either be used in wind power plant models or
to represent wind turbines without wind power plant relationships.
The electrical simulation models specified in IEC 61400-27-1 are independent of any software
simulation tool.

This European Standard specifies the technical requirements, the appropriate dimensions and the requirements for testing.  This European Standard applies to castors and wheels (which may include accessories) for manually propelled or power towed industrial applications up to 1,1 m/s (4 km/h). This European Standard does not apply to castors and wheels for furniture, swivel chairs, institutional, hospital beds and driven applications. Castors for specialised applications may also have to conform to other specific standards.

This European standard specifies the technical requirements, the appropriate dimensions and the requirements for testing. This European standard applies to castors and wheels (which may include accessories) specifically for manually propelled or power towed industrial applications at speeds over 1,1 m/s (4 km/h) and up to 4,4 m/s (16 km/h). Pneumatic wheels and drive wheels are excluded from this standard.

This European Standard specifies the technical requirements, the appropriate dimensions and the requirements for testing. This European Standard applies to castors and wheels which may include braking and/or locking devices, specifically for manually propelled use in an institutional environment. This includes for example, shops, restaurants, hotels, educational buildings and hospitals. Castors for specialised applications may also have to conform to other specialised standards.
