𝐖𝐡𝐲 𝐫𝐞𝐚𝐜𝐭𝐨𝐫𝐬 𝐢𝐧 𝐩𝐨𝐰𝐞𝐫 𝐬𝐲𝐬𝐭𝐞𝐦𝐬? In AC power systems, shunt and series reactors are widely used to limit the overvoltage or overcurrent due to short circuits. With more HV overhead transmission lines with long distances and large network capacity, both types are very beneficial. 𝐒𝐡𝐮𝐧𝐭 𝐑𝐞𝐚𝐜𝐭𝐨𝐫𝐬 For extra HV (EHV) lines, the space between the overhead line and the ground naturally forms a capacitor parallel to the line, which causes an increase in voltage along the distance. A shunt reactor must be installed either at the line terminals or in the middle based on the transmission distance, the profile of the line, and the transmitted power.    𝐒𝐞𝐫𝐢𝐞𝐬 𝐑𝐞𝐚𝐜𝐭𝐨𝐫𝐬 The short circuit current on an overhead line may exceed the short circuit current rating of the equipment for larger networks. Upgrading system voltage, upgrading equipment rating, or employing high-Z transformers are far more expensive than installing oil-immersed series reactors.

Excited to invite you to an insightful presentation on the importance of HVDC (High Voltage Direct Current) networks and the unique protection challenges they present. As HVDC technology becomes increasingly vital in modern power systems, understanding how to protect these networks is more critical than ever. In this session, we’ll first delve into why HVDC networks are so essential, covering their role in enhancing power transmission and grid stability. We’ll then explore the common protection methods used in these networks, followed by an in-depth discussion of protective algorithms applied in different fault scenarios. Key factors like speed, accuracy, internal vs. external fault detection, and system reliability will be highlighted as critical aspects of protection strategies. If you’re working in or interested in the future of power systems, energy transmission, or HVDC technology, this is a great opportunity to deepen your understanding of both the theoretical and practical challenges faced by engineers in this field. Don’t miss out – I look forward to seeing you there! #HVDC #PowerSystems #Protection #TransmissionLines #WindFarmHarvesting #CableBasedNetworks #FastProtection #DigitalRelays #SignalProcessing #UniversityofTehran

⚡ Superconductivity: The Future of Energy Transmission and bringing Energy at lower cost ⚡ Imagine a world where electricity flows with *zero resistance*—that’s the power of superconductivity! This cutting-edge technology is not only transforming energy transmission by reducing power losses but, in some cases, it's proving to be more cost-effective than conventional cables . 🌍💡 By eliminating energy waste and lowering long-term costs, superconductors offer a cleaner, more efficient alternative for powering our future.

This article deals with an #islanded #three-#phase #four-#wire #battery-#supported system with integration of #solar and #wind. Voltage and frequency of #point #of #common #coupling (#PCC) are regulated by a #battery-#supported converter. On other side, voltage across stator of wind driven #doubly #fed #induction #generator (#DFIG) is developed by #stage-#I rotor side converter control. After matching with grid code, the stator connects with PCC. #Stage-#II control is based on #field-#oriented control and it is used to activate power loop of controller. Moreover, this control offers required reactive power by DFIG and it also follows reference rotor speed. An improved three phase #comb #sliding #mode #control (#CSM) regulates dc-link voltage of grid side converter and mitigates power quality issues. Dynamic performances during load variation and change in wind speed are handled by this advanced CSM controller. On other hand, double-stage #photovoltaic (#PV) power is fed to PCC via a voltage source converter. This VSC is controlled by #dq-#control, which regulates dc-link voltage of corresponding converter and also improves performance during solar dynamics.----Sudip Bhattacharyya, Bhim Singh More details can be found at this link: https://lnkd.in/grynv44q

Illustrative case study! 😲 Regarding the resistive option using fifteen 5000 kcmil copper cables per circuit, it should be noticed that the temperature distribution of the conductors in operation leads to a thermal stress on the middle cable of the lower layer, that acts as a bottleneck of the current rating. Adjacent cables of the upper layer would be much less heated and may appear as oversized. Interesting potential application of the IEC 60287-1-3 standard (involving a complex impedance matrix) to check the effective currents in the conductors and metal sheaths of the cable (each of them depending on the temperature of the metal component). The cable engineer must pay attention to the phase arrangement of the cables, to avoid the risk of unbalanced currents. The case study is much more than a thermal study! A benefit of the superconducting alternative. ⚡ Poke Collin Edwards, Darin Lawton, PE, Arnaud ALLAIS, Nicolas LALLOUET.
