Single-phase reactive power controller - multicomp F144-xxx-3
The microcontroller-controlled multicomp F144-xxx-3 records all network data relevant to the control of small systems via A/D transformer inputs. After calculating the required compensation power to achieve the desired target cos φ, the available capacitor stages are automatically switched on or off with a few switching operations. Programming is menu-assisted and is performed with two buttons. System-specific values are stored in a non-volatile memory. Each stage can be switched individually via the built-in manual-0-automatic function.
Highlights
- Detecting and compensating for the missing compensation power in case of recovery into the energy provider network
- Rapid compensation with few switching operation
- Display with two-line LC display, stage status an recovery
- Manual-0-automatic switch separately programmable for each stage
- Integrated temperature measurement

*4-quadrant operation: As energy costs are becoming increasingly important economically, more and more distributed power generation plants will be set up. During low-load periods, this can result in energy being fed back into the supply network. Therefore, all possible states concerning consumption and the provision of active and reactive power must be taken into account for the control system. For example, if asynchronous generators are used to generate energy, active power may be fed into the supply network and reactive power taken from the supply network.
