Load management TQ-Load-Management for industrial applications

Is your company consuming too much electricity, and no one knows why? Are you experiencing expensive load peaks where there should be none? These are questions that most manufacturing companies face – especially when they receive an extra electricity bill from their utility company for exceeding their power allotment.

Detect peak loads and control consumption points intelligently

TQ Automation has the answer to this problem. We make it possible to gain a complete overview of energy consumption patterns and implement automated switching of consumption points.

Automation technology in demand-side management makes it possible to implement the various topologies at low cost.

Here is how it works:

For intelligent energy automation, TQ Automation relies on the products from our series. Because this equipment can be installed on-site and on-demand, it is ideal for use in distribution panels.

Hardware and software of the product range are perfectly matched to each other and make the system easy to integrate – even in retrofitting projects. The system can be parameterised quickly and further optimized at a later date. This makes TQ-Automation load management solutions ideal for energy modernization projects in commercial and industrial properties.

The functions at a glance

  • Measures current electricity consumption at any given time
  • Calculates the average load for a 15-minute metering period
  • Calculates the supply rate for an atypical network load
  • Synchronization with metering periods of the electricity provider (utility company)
  • Sequential load shut-off or connection of supplemental electricity generators
  • Optimization of calculated supply rate and/or power input
  • Adjustable time period for atypical network load
  • Demand-side management

Load profile and consumption control

As the diagram shows, the pre-set power limit restricts usage and prevents excess consumption. Based on the measured active power, the software module calculates the average power value synchronously with the electricity meter and forecasts the expected consumption for the current 15-minute measuring period.

If this is likely to exceed the "supply capacity", consumption points are gradually switched off, their power consumption reduced or, if possible, aggregates switched on to generate electricity (as in the figure the CHP unit).

Sequential load disconnection

The sequence for shutting off consumption points or adding supplementary generators can be programmed individually, along with minimum shut-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 the 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 (building’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 (building’s) power input. The switch-off sequence is reset at 60-second intervals.

Avoiding peak loads

The term "peak performance" describes the peak performance that an industrial or commercial company demands. This power is normally determined over 15 minutes at a time. The higher the peak power, the higher the cost. The goal of every company must therefore be to keep peak performance and thus costs as low as possible.

Full control through optimized load cut-off

  • Electricity consumption points are shut off according to a pre-set sequence
  • Electricity generators are turned on accordings to the shut-off sequence (BHKW, NEA generator, switching photovoltaic systems, battery storage)
  • Specific characteristics of consumption points are taken into consideration – to protect the respective device – to ensure minimal operation – if necessary to preclude shut-off during main usage times
