Disconnect grids securely
Reliable safety switch point between private power generators and the public grid
An automatic switch point monitors the transfer between small private power plants, for instance photovoltaic systems, and the low-voltage grid of the energy supply company. Large power plants are controlled and monitored directly by the energy supply company using remote technology; for the countless private power generators, however, this method is too costly and thus uneconomical. Automatic switch points are therefore used at small private power plants but these have been frequently prone to faults up to now. TELE is now combating this with a new, fail-proof, automatic switch point. The solution is not only low-cost but also complies with the corresponding VDE (the German Association for Electrical, Electronic &Information Technologies) standard and is thus approved for operation in public grids.
In the event of a power failure or a fault in the grid of the energy supply company, small private power plants must be disconnected immediately from the public low-voltage grid to prevent the unintentional feed-in of private generation systems into the public grid. Without the immediate disconnection from the grid, the maintenance personnel would be put at risk on the one hand, and on the other, consumers could be exposed to impermissible voltages and frequencies. The monitoring and the automatic disconnection are done by an automatic switch point. Systems used up to now, however, had the disadvantage that several parallel-switched switch points on one grid point could disrupt each other or also be impaired by strong levels of interference from other systems (for instance ripple control systems). There were therefore frequently errors in operation.
Single-fault tolerance
With the new automatic switch point of TELE, this can now no longer happen. It has a redundant design and constantly monitors the grid quality by checking the voltage, frequency and isolated operation. If predefined threshold values are exceeded in the event of a fault, the protective device disconnects the private grid from the public grid by means of two switches arranged in series. The system thus guarantees single-fault safety – maintenance of the automatic switch point is not required. The new TELE solution also complies with DIN-VDE 0126-1-1 and the high requirements of the Austrian Institute of Technology (AIT). The document of compliance, which is standard in the industry, has been issued for the German market.
