Relay Protection Design for Wind Power Systems
Abstract−To avoid undesirable disconnection of healthy wind generators (WGs) or a wind power plant, a WG protection relay should discriminate among faults, so that it can operate instantaneously for WG, connected feeder or connection bus faults, it can operate after a. For those not familiar with the different elements that form a WEP, commonly known as a Wind Farm, this report introduces a description of the different elements comprising a wind farm and how their unique characteristics may be considered to provide a proper design. First, the amplitude and attenuation characteristics of short circuit current in different types of wind turbines are analyzed, as well as the contributing factors to short-circuit current in wind farms. Protection of Wind Electric Plants is a report covering engineering considerations for the design of protection systems and present relay protection and coordination practices at wind electric plants. Abstract—A wind electric plant (WEP) is made of many wind turbine generators spread over a large area and includes many subsystems that need to be protected.

What are the relay protection design systems
Relay protection is the discipline of designing schemes that detect faults, coordinate relays, and isolate equipment without outages. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.

Relay protection complies with
The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current,, reverse flow, over-frequency, and under-frequency. The scope of TC 95 is the standardisation of measuring relays, protection equipment, and protection functions embedded in any equipment or systems used in various fields of electrical engineering covered by the IEC, including combinations of devices and functions that form schemes. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers.
