With a view toward the future of e-mobility and the increasing need for energy to power it, industrial buildings will face a number of challenges. Intelligent automation systems will be required to avoid load peaks and the risk of blackouts.
TQ Automation has developed an innovative approach for solving these problems with the DM100, a system that offers an entire new set of possibilities for integrating e-charging infrastructure. It enables a unique combination of dynamic load management and intelligent optimization of energy costs – including blackout protection and overload protection.
For intelligent load management, TQ Automation relies on its own product series. Because this equipment can be installed on-site and on demand, it is ideal for use in distribution panels.
Commissioning and parameterisation via integrated HMI. A master monitors the supply or connected load and switches off consumption points or generators as required.
The sequence for shutting off consumption points or adding supplementary generators can be programmed individually, along with the minimum shot-off times and restrictions (e.g. times when certain equipment cannot be shut down. The switch-off levels are adjusted dynamically within the metering period, in accordance with pre-set time delays (see Figure 2). For example, when the metering period starts, the delay time is 120 seconds. It decreases incrementally during the metering period, until it is just 10 seconds.
If the current power consumption exceeds the (facility’s) power input, the switch-off sequence (shut-off level) is increased in 10-second intervals until it is once again safely within the range of the (facility’s) power input. The switch-off sequence is reset at 60-second intervals.
