Enhancing Power Quality: SVG vs. APF   🌟 Static VAR Generator (SVG): SVGs are essential for dynamic reactive power compensation. They stabilize grid voltage and improve power factor by injecting or absorbing reactive power. With fast response times, SVGs ensure voltage stability and can also mitigate harmonics to some extent.   ⚡ Active Power Filter (APF): APFs are designed to combat harmonic distortion from non-linear loads. By injecting counteracting currents, they reduce harmonics and improve power quality. APFs can also offer load balancing and limited reactive power compensation.   📈 Choosing the Right Solution: SVGs focus on voltage regulation and reactive power, while APFs target harmonic reduction. Both play crucial roles in maintaining efficient and reliable power systems.   Explore how Yingtong (YT) Electric can support your power quality needs.   #PowerQuality #ReactivePower #Voltage #Harmonic #SVG #APF #ElectricalEngineering #Grid #PowerFactorCorrection #EnergyEfficiency #YingtongElectric #IndustrialAutomation #SmartGrid #SustainableEnergy

When AC power is not available or practical, solar power is the solution. ELTEC’s solar powered pedestrian crossings are sized for geographic locations including average weather conditions, number of crossings (activation time), and electrical load for optimal effectiveness guaranteeing sufficient power for the flashing beacons throughout the year. As specified by the FHWA, it is not acceptable to dim signal indications or flashing beacons in daylight conditions. #SolarPowered #pedestriancrossing #pedestriansafety #elteccorp

I have been receiving numerous inquiries lately about selecting the right ZLD technologies, especially regarding new options like MVRE and TVR as alternatives to MEE. Dear readers, In Multi-Effect Evaporators (MEE) are commonly employed to concentrate solids in effluent and reclaim water from the final stages. The focus is on minimizing steam and cooling water usage by reducing steam consumption. In the first stage, the evaporated water now steam from 1st column instead of being sent to the condenser, and is sent to heat the next stage column for heating. In Thermal Vapour Recompression (TVR) the jet pump compresses this steam and is reused to heat the effluent again, it acts as an additional stage only. So there are benefits but limited to the same that we would get by adding an additional stage. So TVR uses less steam as compared to single stage evaporator. Mechanical Vapor Recompression (MVR) uses a centrifugal force (by electrical blower) to add the energy after 1st stage and keeps on reusing the same steam. You can have single or multiple stages in MVRE depending on the temperature delta. MVRE uses at least 50% lesser steam and 80% less cooling water as compared to MEE. So steam or energy consumption wise MVRE is lowest followed by TVR and then MEE. But how do you select the technology? It all depends on the cost of steam and electricity cost. MVRE though cheaper in steam consumption is expensive due to the Blower or compressor being expensive and Capex being on a higher side. MVRE also requires electricity, so places where electricity is costlier also need to have this in mind while selecting. Overall I would recommend a very careful comparison and evaluation of Total cost of ownership rather than just considering Capex and Opex. Do write to me for any queries or any consulting services in this regard. Let's simplify and kickstart a discussion on this topic. #ZLD #ZLDtechnologies #MVRE #TVR #MEE #watermanagement

High temperature iron rod test: By comparing the solar cable irradiated by electron beam and the solar cable not irradiated by electron beam, it can be clearly seen that the solar cable not irradiated melts immediately after contacting the iron rod and exposes the conductor. #Solarcable #PVcable #Electronbeamirradiation #Firekillersolarcable

🖥️ 📲 💻 Lubrication oil as an indicator of your wind power plant's condition 🌬️ If contamination particles build up in your wind turbine's drive train, this can lead to breakdowns, expensive damage and time-consuming maintenance work. It doesn't have to be that way. Our HYDAC Metallic Contamination Sensor prevents failures with clever monitoring. It quickly and reliably detects metallic wear particles in your wind power plant before they cause any damage. Industry-approved and certified sensors automatically record, visualise and store critical system states and anomalies. Our Condition Monitoring Package is an expandable modular system solution for extensive, fluid-related data with up to three sensors. A retrofit with the HYDAC CM-Kit and specific special requirements can also be implemented. You can find more information on "drive train monitoring for wind turbines" in our download area: https://lnkd.in/eEabqY7F #hydac #hydacgroup #hydacinnovation #windpower #windenergy #renewable #fluidmonitoring #systemavailability #conditionmonitoring #smart #retrofit

When your eco-friendly solar panels somehow catch fire, damaging the AOV rooflights 🧯🔥 The Independent has revealed that the number of solar panel fires has risen sharply in 2023 compared to previous years, leading to mounting concern among fire safety experts. The data, acquired by the newspaper under freedom of information rules, showed that 66 fires related to solar panels had occurred since the beginning of 2023 up to July. This is a stark increase when compared to 63 fires for the whole of 2019. It was also found that there were “six times the number of fires involving solar panels last year compared with 10 years ago” #fire #aov ADL Group 0208 248 4011 [email protected]

A simple, graphical view of what happened in the grid event last Tuesday 13/2/2024 Dual 500 kV lines run across the state of Victoria like a backbone. They are shown in red in the picture below. Cutting them is very bad. Power generation prior to the event is shown by yellow circles. According to AEMO' s preliminary report: • The 500 kV lines blew down. This cut off Melbourne from a large amount of generation in the west of the state • Loy Yang A Tripped. I don't know why, no doubt AEMO will have something to stay in the final report. • Dundonnell wind farm tripped. I understand this may have been due to a special protection scheme. This scheme is required to prevent voltage collapse by maintaining the system strength in this area. Not surprisingly this was reduced by the loss of the backbone. It didn't really affect Melbourne, since it was to the west of the cut-point. So now the system looked like the image below. AEMO cleaned up the system by temporarily dumping some of the load in Melbourne, sacrificing it to keep the rest of the system safe. What can we do to prevent this from happening in the future? Installing more transmission lines in parallel to the 500 kV backbone would make the system more robust. But that isn't going to happen, people hate them. What could help is more batteries in the Melbourne area. It would make Melbourne less vulnerable to being cut off from its power supplies.
