Microgrid dual protection access
This paper presents a method to protect microgrids (MGs) through coordination of directional overcurrent relays (DOCRs). The new formulation is subjected to restrictions of pre-established time intervals to guarantee the primary and backup functions of each relay. . If microgrids are to become ubiquitous, it will require advanced methods of control and protection ranging from low-level inverter controls that can respond to faults to high-level multi-microgrid coordination to operate and protect the system. Microgrids are inherently dynamic systems due to their. . With dual protection microgrid access, both threats get neutralized before your surgeon's scalpel twitches. Traditional DOCR coordination is. . [pdf]
Direct drive wind turbine dual wheel wind
The use of generative design as an alternative to typical structural optimization techniques opens the door to new methods of manufacturing. In this study, generative design techniques were used as an a. [pdf]FAQs about Direct drive wind turbine dual wheel wind
What is a direct drive wind turbine generator?
A direct drive wind turbine converts rotor rotation to electrical power directly, without the use of a gear box. Traditional wind turbines use gearboxes to step up the rotational speed (about 100x) from the rotor to the generator, which makes electrical power. This article discusses direct drive wind turbine generators, including pros and cons.
What are the advantages of direct-drive wind turbines?
Direct-drive wind turbines have been implemented in offshore wind developments contributing to a wide range of advantages, such as overall mass reduction, simplification of the structure and compactness.
Why do direct drive turbines need a gearbox?
The high maintenance cost for gearboxes is one of the main motivations for direct drive turbines. Direct drive machines have no need for a gearbox; a special generator creates electrical power directly from the (low speed) rotor rotation. increased efficiency (no power lost in the gearbox, better efficiency at lower wind speeds).
Can generative Design Optimize multi-MW offshore wind turbine electrical generators?
The results achieved for the structure in question during the generative design process open the door to a distinct perspective of the optimization of multi-MW offshore wind turbine electrical generators as a wide range of structural configurations can be discovered and evaluated.
