The LVRT test provides transmission network operators and wind turbine manufacturers with reliable voltage dip capability results.
As India aims high to broaden their renewable energy capacity and takes more stringent measures to improve the quality, DNV GL launches its LVRT testing services, following up with the Central Electricity Regulatory Commission's (CERC) mandate to make these tests grid compliant for all operating wind turbines.
It is important to note that the output characteristics of DG in downstream of fault point are only associated with line impedance characteristics, so that the LVRT model can only be applied to the DG in upstream of fault point.
Although the LVRT standards of different types of inverter based DG are different, the control idea of them is the same.
Recently in 2014 the Taiwan government reveals the effect of LVRT in first offshore wind farm planning which is analyzed by using various FACTS devices according to their Grid Code requirement .
The implementation of LVRT requirement needs some of the modification in system design by installing some additional hardware or by improving the control strategy of power electronic equipment in case of DFIG.
Due to these high transient currents and overvoltage during this LVRT event, special protection techniques are needed to protect the DFIG during these events.
The required LVRT behavior is defined in grid codes issued by the transmission system operators in order to maintain system stability Grid codes vary from country to country according to the requirement.
I am convinced the LVRT
solutions of w2pS can play as important a role in the wind sector in China as they did in Spain.
With the SmartSet Coupling, in contrast, the plant seamlessly transitions to normal operation following an LVRT
These best-in-class outdoor inverters are designed to deliver maximum yield for the lowest cost, and have all the grid code integrated features needed for compliance with advanced European and global power standards, including LVRT
(low-voltage ride through), Reactive Power Control, Frequency and Voltage controls.
