Abstract:For energy supply in the Arctic regions, hybrid systems should be designed and equipped to ensure a high level of renewable energy penetration. Energy systems located in remote Arctic areas may experience many peculiar challenges, for example, due to the limited transport options throughout the year and the lack of qualified on-site maintenance specialists. Reliable operation of such systems in harsh climatic conditions requires not only a standard control system but also an advanced system based on predictions concerning weather, wind, and ice accretion on the blades. To satisfy these requirements, the current work presents an advanced intelligent automatic control system. In the developed control system, the transformation, control, and distribution of energy are based on dynamic power redistribution, dynamic control of dump loads, and a bi-directional current transducer. The article shows the architecture of the advanced control system, presents the results of field studies under the standard control approach, and models the performance of the system under different operating modes. Additionally, the effect of using turbine control to reduce the effects of icing is examined. It is shown that the advanced control approach can reduce fuel consumption in field tests by 22%. Moreover, the proposed turbine control scheme has the potential to reduce icing effects by 2% to 5%.Keywords: wind energy; hybrid systems; harsh climatic; pitch-control; intelligent control system; icing prediction; predictive analytics; adapted technologies

Vvkb Diesel Tent Heater is a gasoline or diesel fired parking heater for a rapid and constant supply of heat, specially designed for camping and outdoor activities. With an independent fuel tank, compact, easy to install and ergonomic design, it is a perfect choice for on the move campers.
With the Japan Kyocera ignition plug, inbuilt thermostat and intelligent control system, VVKB Diesel Tent Heater guarantees a high thermal efficiency. It consumes less fuel and emits virtually no soot.
A small ThermoConnect control unit is installed in the vehicle so that the app and the parking heater can communicate with each other. The control unit ensures a smooth connection and can also be retrofitted without any problems. The app is conveniently activated and linked via the QR code. You can then maintain and change your personal data at any time via "my.webastoconnect.com". The mobile connection is already included in the control unit and software updates are carried out automatically.
With most of the country in the grips of what feels like a colder than average winter, many RV owners will be considering fitting some sort of heating to their caravan, camper or motorhome. If free camping is on the agenda, then a diesel-fuelled ducted heating system is the obvious choice. But which one do you choose? The expensive name brand or a cheap unit from China? In this article, we look at the pros and cons of both and speak to owners and repairers about their experiences so you can make an informed choice.
When it comes to diesel heaters, there are the trusted brand names in such as Erberspacher and Webasto, as well as a seemingly endless number of suppliers of cheap copies available online, predominantly sourced from China. The price difference between the two options is considerable. The entry-level Erberspacher D2, which has a rated heat output of 2200 watts, sells for around $1900 whereas the price for a 5000-watt heater from China can be as little as $270 online. It's a huge price differential and explains the appeal of the Chinese units.
However, the Chinese heaters tend to get a bad reputation for reliability, parts availability and, most importantly, safety. Chris Emmerson of CJE Caravan Repairs has seen a lot of dodgy products come through his workshop, but increasingly he is being asked to fix issues associated with cheap ducted diesel heaters.
However, it appears it's not all bad news for buyers of the cheap heaters. For a start, there is a huge online community of owners who have posted lots of supporting material on the internet, including a vast number of YouTube videos detailing the installation process as well as troubleshooting problems.
Two common complaints about some cheap diesel heaters are noisy fuel pumps and the exhaust systems. It appears these units may not be supplied with adequate silencers making life for you and your neighbours particularly unpleasant. We recently camped next to another van fitted with what we suspect was a cheap diesel heater due to the rather unpleasant noise coming from the exhaust port. It was certainly much louder than many others we've encountered.

Chris told us he believes many of these cheap heaters are made from inferior quality materials. For example, the thickness of the metal used for the heat exchanger, which is prone to burning through to the heated air outlet allowing exhaust fumes to escape. Not only is this a fire risk, but it also means carbon monoxide could enter the living space of the caravan.
The DIY installation of these diesel heaters can also present overvoltage issues. Chris told me he had a customer complain that when he first used his heater, he had a strong smell of diesel fuel inside the caravan. Upon inspection, Chris found the owner had installed the unit himself and had cable-tied the fuel line to the exhaust outlet! Not the smartest move in the world.
Chris admits that these installation issues can happen with any brand diesel heater. However, he did point out that the installation instructions that come with the brand-name heaters are much clearer than the cheaper alternatives.
Chris recommends that if you do have one of these cheaper diesel heaters installed in your RV that you have it inspected by a specialist to ensure it is installed properly and working correctly. As an added safety measure, he also recommends installing a carbon monoxide alarm near the sleeping space of your RV. Most hardware stores and caravan accessory retailers sell units that are suitable for caravans and motorhomes. Follow the mounting instructions to the letter, too.
A user from the Facebook group mentioned earlier contacted me to describe his experience with his diesel heater. He switched the unit on after installing it only to have the cabin of his motorhome fill with noxious white smoke 45 minutes later. He was unable to get any technical assistance from his supplier, instead receiving a full refund.
The reality is that as long as there are expensive name-brand goods that are popular, there will be cheap copies available online. Some will be good, and some will be very ordinary. When it comes to diesel heaters, you can almost purchase ten cheap units before you spend the same amount of money for a single name brand item. With a bit of research and good fortune, you may end up with a good one or only having to replace one faulty unit, and even then you would still be way ahead in terms of cost.
But cheap doesn't necessarily mean safe. If you intend to purchase a ducted diesel heater, we recommend that you stick to the name brands for peace of mind. However, if you cannot afford one, purchase a cheaper unit from a reputable Australian seller. Make sure it has the safety features of the more expensive brands and that it is supported by a local warranty with spare parts availability. 2b1af7f3a8
