IEC 61400-27-2 specifies procedures for validation of electrical simulation models for wind turbines and wind power plants, intended to be used in power system and grid stability analyses. The validation procedures are based on the tests specified in IEC 61400-21. The validation procedures are applicable to the generic models specified in IEC 61400-27-1 and other fundamental frequency wind power plant models and wind turbine models.

The validation procedures for wind turbine models focus on tests for response to voltage dips, voltage swells and reference point changes. Those validation procedures refer to the wind turbine terminals.

The validation procedures for wind power plant models focus on tests for response to reference point changes as well as voltage dips and voltage swells. Those validation procedures refer to the point of connection of the wind power plant.

The validation procedures specified in IEC 61400-27-2 are based on comparisons between test results and simulations, but they are independent of choice of software simulation tool.

IEC 61400-27-1 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.

This part of IEC 60095 is applicable to lead-acid batteries used primarily as a power source for the starting of internal combustion engines, lighting and ignition (SLI) of motorcycles and other power sport vehicles. The nominal voltage is 12 V or 6 V.

Test definitions and criteria in this document are written for batteries with a nominal voltage of 12 V only. For batteries with a nominal voltage of 6 V all voltages have to be divided by two.

The other power sports vehicles in this document are snowmobiles, personal water crafts and all-terrain vehicles.

This document is not applicable to batteries for other purposes, such as the back-up power source, auxiliary equipment of internal combustion engine vehicles and e-bike.

The object of this document is to specify

-general requirements;

-size, essential functional characteristics, relevant test methods and results required;

This part of IEC 60095 is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as power source for the starting of internal combustion engines (ICE), lighting and also for auxiliary equipment of ICE vehicles. These batteries are commonly called “starter batteries”.

The batteries under scope of this standard are used for micro-cycle applications in vehicles which can also be called Start-Stop (or Stop-Start, idling-stop system, micro-hybrid or idle-stop-and-go) applications. In cars with this special capability, the internal combustion engine is switched off during a complete vehicle stop, during idling with low speed or during idling without the need of supporting the vehicle movement by the internal combustion engine. During the phases in which the engine is switched off, most of the electric and electronic components of the car need to be supplied by the battery without support of the alternator. In addition, in most cases an additional regenerative braking (recuperation or regeneration of braking energy) function is installed. The batteries under these applications are stressed in a completely different way compared to classical starter batteries. Aside of these additional properties, these batteries need to crank the ICE and support the lighting and also auxiliary functions in a standard operating mode with support of the alternator when the internal combustion engine is switched on. All batteries under this scope need to fulfil basic functions, which are tested under application IEC 60095-1.

The object of this standard is to specify the general requirements and methods of test specific for the lead-acid Batteries used for Micro-Cycle Applications.

This IEC Standard is applicable to batteries for the following purposes:

•    Lead-acid batteries of the dimensions according to 60095‑2 for vehicles with the capability to automatically switch off the ICE during vehicle operation either in standstill or moving (“Start-Stop”);

•    Lead-acid batteries of the dimensions according to 60095‑2 for vehicles with Start-Stop applications with the capability to recover braking energy or energy from other sources.

The Li-ion technology is excluded of this Standard.

NOTE - The applicability of this standard also for batteries according to 60095‑4 is under consideration.

This international standard specifies performance requirements for electronic controlgear for use on DC or AC supplies up to 1000 V (AC at 50 Hz or 60 Hz) and with an output frequency which can deviate from the supply frequency, associated with LED modules according to IEC 62031. Controlgear for LED modules specified in this standard are designed to provide constant voltage or current. Deviations from the pure voltage and current types do not exclude the gear from this standard.

NOTE 1 The tests in this standard are type tests. Requirements for testing individual controlgear during production are not included.

NOTE 2 Requirements for controlgear which incorporate means for varying the output power are under consideration.

NOTE 3 It may be expected that controlgear complying with this standard will ensure satisfactory operation between 92 % and 106 % of the rated supply voltage, taking into account the specifications of the LED module manufacturer.
