Data Logger and Power Plant Controller

Data Logger & Power Plant Controller

The Q.reader offers reliable and flexible solutions for the park control of utility scale and industrial and commercial (I&C) PV power plants. The Data Logger can record several thousand data channels with a resolution of up to one second. With functions like voltage regulation, reactive or active power control, and control of power factor at the grid connection point all Distributed Network Operator (DNO) requirements are provide to maximize grid stability. The real time Linux based Q.reader has multiple input and outputs for the signal connections. The module concept allows flexible upgrade of the number of inputs and outputs. The Gantner Instruments Plant Controller provides all functionality for the Smart Grid for today and tomorrow

Field Point Extension "FPE"

Field Point Extensions are fully customized  add-on cabinets to the “Q.reader” data logger which provide data acquisition within the entire PV plant, such as string level (current, voltage), inverter data, meteorological data from weather stations, grid measurements and other state variables (switch gear, transformer status). Usually one FPE per transformer station is applied and information from all FPEs will be sent to the central data logging and control unit QRC by fiberoptic.

Wireless module

Wireless module

Thanks to the wireless RF.bloxx 101 it is possible to provide string monitoring without either communication cable nor power supply cable. This is a big advantage especially for retrofitting PV power plants with string monitoring devices.

Distributed IOs

Distributed IOs

With help of our Distributed I/Os we are flexible to extend our measure and control network. Distributed input/output systems generally send control signals and read sensor measurements over a communication network. The network links the central Q.reader controller to several nodes located around the power plant.
