The Case For Surge Protection Systems For Wind Turbines

The continual change in climate conditions combined with the increasing dependence upon fossil fuels has dramatically increased interest in sustainable, renewable energy resources worldwide. One of the most promising technologies in green energy is wind power, which, except for high startup costs, would be the choice of many nations worldwide. For example, in Portugal, the wind power production goal from 2006 to 2010 was to increase to 25% of the total energy production of wind power, achieved and even surpassed in later years. While aggressive government programs pushing wind and solar energy production have expanded the wind industry substantially, with this increase in the number of wind turbines comes an increase in the likelihood of turbines being struck by lightning. Direct strikes on wind turbines have become recognized as a serious problem, and there are unique issues that make lightning protection more challenging in wind energy than in other industries.

Promotion of Green Energy Through Cost Reduction

Both solar power and wind power are internationally recognized as crucial components to the future of life in nearly every industrialized society on Earth.  The fossil fuel industry still dominates most cultures, with energy produced from the burning of coal, oil, wood or other elements used to produce heat and electricity, power our automobiles and cook our meals.  However it is widely recognized that there are multiple alternative methods of producing that electricity and energy including wind and solar power.

Wind Turbine Surge Protection

Raycap has a full suite of surge protection products available for wind turbine applications. From Strikesorb ,the premier offering from Raycap to various DIN rail mounted protection products and surge and lightning monitoring.  As we enter a time in history when the push towards green energy and technology is continually causing more wind farms to be built, and current wind farms to be expanded, both turbine manufacturers and wind farm owners/operators are increasingly aware of the costs associated with lightning strikes.  The monetary damage that operators sustain when there is an instance of a lightning strike comes in two forms, the costs associated with replacement of machinery due to physical damage and the costs associated with the system being offline and not producing power.  (more…)

Solar Power Surge Protection Devices

Solar power production is an industry that has been in the spotlight in the American media landscape for several years as the push towards “green” energy production gains popularity.  Generally discussed in the same vain as wind power production, these two sources of renewable energy are favored by most environmentalists due to their negligible impacts on the environment. When compared to fossil fuel energy production, both solar and wind power are far and away the more preferable choice due to their low environmental impact and elimination of greenhouse gasses produced through the burning of fossil fuels. Greenhouse gasses and known and most widely recognized as having serious impacts on our worldwide climate, and the harvesting of the fossil fuel itself has also had serious detrimental effects on our landscapes and living conditions in production areas. With the advent of wind and solar power as viable alternatives that have the promise to fulfill demands, the discussion of complete elimination of fossil fuels as a power source, and the moving to greener production methods, becomes a very relevant one.  The hindrance at this point in time are the production costs which directly dictate the price of the energy that is paid by businesses and consumers. While there is generally no argument against wind and solar power as a method of producing power, the push back comes in the form of the prices that must be paid.  (more…)

Solar Power Surge Protection

Photovoltaic (PV) systems are at risk for significant ongoing damage and revenue losses to power plant operators as a result of damaging electrical storms.  Factors ranging from their remote locations and extensive layouts, to direct or indirect lightning strikes affecting system components, can all create revenue losses experienced as interruptions in power generation and equipment replacement costs.  Significant losses are sustained if a PV system is offline for even a few hours, let alone days or weeks.  The only way to mitigate damages caused by lighting surges is by avoiding the potential effects of surges with surge protective devices (SPDs) installed at inverter locations, inside combiner boxes, as well as at various other points within the PV power facility.

Solar Surge Protection

Solar farms using photovoltaic (PV) systems to produce clean energy for consumer or industrial use are subject to serious potential damage due to their specific physical makeup.  The necessity to cover wide expanses of land without having direct sunlight compromised by surrounding structures makes solar installations vulnerable to lightning strikes.  Combine this threat with the physical wear and tear of exposed open spaces caused by wind, rain and other natural events, and there exists a situation where replacement costs must be figured into ongoing operations.  It must be assumed that components of the system will be significantly damaged over time and need repair and replacement.  While there is little that technology can do to stop wind and rain damage, surges as a result of electrical storms can be prevented effectively with intelligent choices of  surge protective devices (SPDs).  All SPDs are not created equal, and offer different levels of solar power surge protection.

Photovoltaic Surge Protection

Photovoltaic surge protection systems are some of the most effective methods of increasing profitability of solar power plant installations. Operators of PV power systems understand the significant costs associated with equipment replacement or loss, and are also well aware of the risks of damage due to remote locations and extensive layouts. While inclement weather and natural environmental factors pose significant risks to solar installations, perhaps the most critical risk factor is lightning strikes to facility components. Lightning strikes create damage in the forms of both equipment destruction as well as revenue losses associated with systems being knocked offline for extended periods of time. The only effective means of protection is avoidance of the surge itself through installation of SPDs (surge protective devices) within inverter locations, string boxes as well as various other strategic points within the solar facility boundaries.

Do You Operate A Wind Farm?

Over the course of the last five years or so, the nationwide interest in clean energy production has sparked additional demand for larger industrial installations of clean production facilities. The growing demand has produced the need for both larger facilities but also safer and more productive systems. The main issue facing these types of installations is the production of energy at a price which can match fossil fuels. The affordability of energy produced through “less clean” means has historically lead to the stagnation in advancements within the clean energy sectors, simply due to the lack of funding to develop the technologies. As we come closer and closer to prices which are equal, we find that technological exploration into improvements can propel clean energy production to a place which is unmatched as far as affordability.

Wind Turbine Protection From Electrical Surges

Electrical surges are one of the greatest threats to wind turbines, and the operation of the systems attached to them. While damages to wind turbines as a result of the harsh natural climates they are exposed to is expected, the damage caused through lightning strikes stands out as especially significant. Due to their natural attraction of lightning by their physical makeups of being taller than surrounding structures and generally placed in remote areas, wind turbines themselves must have an assumed maintenance or replacement plan figured. This type of plan cannot accurately predict lightning damage due to the inconsistent nature of it, as well as the multiple forms of damage that can occur. A direct lightning strike to a wind turbine will undoubtedly produce structural damage to the location of the strike, and there is little that can be done as far as protective measures that will extend equipment lifespans from this type of damage. The coupling of added volumes of electricity into power lines which are directly attached to circuit driven equipment, however, does have an ability to have damage minimized or avoided. Through installation of Raycap Strikesorb SPDs at strategic locations within the wind turbine structure, the inevitable surge can be effectively prevented from reaching it’s destination. (more…)
