Description

DNV GL
DNV GL (formerly KEMA) is of course a household name among engineers. Known far beyond our borders, KEMA's high-voltage and short-circuit laboratories, among others, are legendary. DNV GL maintains its top position in testing and also development!

There are many new angles in the field of energy distribution. Distribution cannot ignore the demands of the times either. On the one hand, the influence of incorporating sustainable energy in medium-voltage grids (intelligent grids) and the requirements of higher efficiency and cost optimisation of medium-voltage grids.

Incorporating sustainable generation in medium-voltage grids
There are many initiatives in the field of the development of intelligent grids, to which KIVI Elektrotechniek has also devoted a lot of attention, but generation units with a lot of power electronics in medium-voltage grids have not yet been tested frequently.

The Flex Power Grid Laboratory (FPGL) in Arnhem is an independent medium-voltage laboratory for testing and investigating (grid-connected) power electronics under complex realistic grid situations. This laboratory is one of the few capable of testing the correct functioning of decentralised power generation units under realistic grid conditions. It simultaneously verifies and validates the hardware (components) and controls (ICT) of a unit before it is integrated into a larger system (e.g. the distribution grid). The FPGL is the only laboratory capable of testing such combinations 'real-life' at medium- and high-voltage levels.

Live testing of medium-voltage cables
In the Netherlands, some 100,000 km of medium-voltage cables lie underground, representing a huge investment but also having a significant impact on failure rates. A unique condition monitoring system has been developed in the Netherlands, which can continuously monitor the condition of this cable and thus spot weak spots before they lead to a failure. Moreover, this system has recently been expanded to include fault location so that, even if the cable fails due to external influences, such as excavation damage, this fault is immediately detected and located. This, in addition to preventing faults, now also greatly reduces the time period of a potential failure. During the presentation, the principles of this advanced system will be explained and several interesting 'real life' cases will be discussed
