6 Frequently Asked Questions about “Wind turbine protection system”
What is a protection scheme in a wind electric plant?
Protection schemes within these types of equipment are designed by their manufacturers and are integral to the equipment. Wind Electric Plants are composed of many wind turbine generators (WTGs) which are connected to a collector substation through a collector system.
What is a wind turbine protection scheme?
The wind turbine protection scheme may include voltage and frequency relaying to protect the generator. For example, some wind turbines may trip for frequencies at or below 95 percent of nominal, or above 103 percent of nominal, with an appropriate time delay.
Do wind turbine generators and static VAR sources need to be protected?
Although the report addresses coordination with wind turbine generator protective devices and static VAR sources, protection of the wind turbine generators and static VAR sources themselves is not included. Large WEPs are becoming more prevalent as generation sources on the power system.
What is a wind electric plant?
Wind Electric Plants are composed of many wind turbine generators (WTGs) which are connected to a collector substation through a collector system. The collector system is connected to the main substation or Point of Interconnection (POI) where the voltage is stepped up to the transmission voltage level.
How many turbines does a wind power plant have?
By comparison, a large modern wind powered generation plant will have a large number of small generators – perhaps 80 to 100 turbines each with a typical rating of 1.5 MW to 3.0 MW. Larger units have become available mostly in offshore wind farms.
How can a wind power plant assist the grid during contingencies?
It is important to consider applicable regulatory requirements, such as low-voltage ride through (LVRT), to enable the wind power plant to assist the grid during contingencies. Maintaining adequate power quality is another such consideration.
