Comparison of several Low Voltage Ride Through Attached Equipment
2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019The power plant auxiliary drive system will work abnormally or even trip due to frequency converter voltage drops, which might be caused by transient state process of auxiliary power system or the external grid. Low voltage ride through (LVRT) is an effective way to solve the above problem.

Low-voltage Ride-through Capability Characterization of Wind Farms
Electric Power Components and Systems, 2012Abstract This article characterizes low-voltage ride-through capability of wind farms. Critical clearing time has been used in the literature as a measure of the transient stability of induction generators and, hence, an indication for low-voltage ride-through capability of single wind turbine generators.

Low voltage ride through capability of fuel cell generation system connected to low voltage network
2011 IEEE Conference on Clean Energy and Technology (CET), 2011New grid code is expected to require distributed generation units operating parallel with the low voltage grid to ride through low voltage event and at the same time injecting reactive current into the grid. The paper discusses and highlights the problems that could arise and explores the solutions to mitigate these problems.

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
The total real power injected by distributed renewable energy sources (RES) in the low voltage (LV) grids can cause voltage rise effects during light load scenarios. Integrating RES in microgrid architectures can result in improved power quality of the electrical grid, by avoiding the voltage rise effect from occurring and also by providing ancillary ...

Low voltage ride-through enhancement in DFIG-based wind turbine
2016 IEEE Electrical Power and Energy Conference (EPEC), 2016Wind farms are regarded as large-scale power plants with interconnected systems, where all systems interact with each other to improve the efficiency of the plant and thus enhance the quality of the output power. However, the conventional centralized controller is inappropriate for such plants.

Low voltage ride through for a wind turbine based SCAG
2015 3rd International Renewable and Sustainable Energy Conference (IRSEC), 2015This paper develops a control strategy for a large wind turbine based on the squirrel cage asynchronous generator (SCAG). In addition, the transient behavior during Low Voltage Ride Through (LVRT) of the system is studied. To this end, the wind turbine connected to the grid is controlled in such way to inject maximum power into the grid and provide a ...

Low voltage ride through capability of gas engine driven units
22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013Recent developments in European grid code regulations demand the inclusion of decentralized generation (DG) into their requirements. Gas-engine-driven generators, as a part of Europe’s DG, need to comply with these requirements; and therefore procedures to receive admission are formed.

Effect of Low Voltage Ride Through Technologies on Wind Farm
2007 IEEE Canada Electrical Power Conference, 2007Doubly fed induction generators (DFIG) offer many advantage when used with wind turbines. Given their configuration, they are particularly sensitive to grid faults. As many countries now require wind turbine generators to remain connected to the grid during faults, low voltage ride through solutions are being developed to fulfill this new requirement ...
