- The causes of damage are currently unclear and leads to increased vulnerability for society and industry. Therefore, our research are urgent, says Professor Martin Lundmark, Department of Energy Science at Luleå University of Technology.
He is responsible for a research group that studies the impact on the grid when the use of new power dependent technologies, for example in solar and wind power, electric cars and rail technology, introduced online. Changing to energy efficient lighting is one of many cost-effective ways to reduce carbon emissions. A prerequisite for the change to have a positive impact on the environment, is that the new energy lamps last long enough. Today, there are problems with the sustainability problems that may be related to stress changes in the grid.
The new research project, aiming to clarify how new electrical and lighting interact and mains, has just started. The research has attracted much international attention. Companies such as Philips, Osram, Boliden, Skelleftea Kraft, Nordic Light AB and others involved in the project.
- Company reports on electronics inexplicably breaks and problems in the electricity grid, says Martin Lundmark.
But what happens when a new low-power electronics, tested and approved in a laboratory setting, tucked into the network with much larger electrical appliances, such as when Led and electric car charger to be connected together. Today, lack of knowledge and sufficient standards for frequencies well above the normal electrical power system frequency. Scientists measure how different light sources are affected in different kinds of plants. From this developed models to test various measures, such as how to install the lights on, which reduces electrical appliances influence on each other. The goal is to minimize the risk of lighting installations have shorter life through the influence of other devices connected to the mains.
