Powertek's UFIX-3ph Ultrafast import-export sensor detects direction of import/export power and energy flow instantly, allowing real time control of excess energy found in Micro-Grids, allowing instant control, directing excess Wind and PV energy into storage banks - preventing unauthorised export to a utility. EtherNet, Modbus RTU/ASCII or Profibus
The Powertek Model UFIX-3ph Ultrafast import-export energy detector and energy controller, is used in MicroGrids to direct energy flow whne these is a surplus. The UFIX-3ph works with all waveform types from sinewaves to on/off dutycycle and complex drive applications, 5Hz-20kHz range. It computes all AC parameter using high-speed simultaneous sampling with precise internal analog-to-digital converters, which provide fast accurate ac measurements regardless of waveshape or frequency.
The UFIX-3ph includes computation of real power watts (W), real power factor (PF) reactive power (VAr) delivered to a load. Its Bi-directional capability allows power and energy to be measured incredibly fast in either directions (import export), with trigger outputs of import and export. Especially in MicroGrid applications, Locomotive, Electric vehicle where motoring and regeneration occurs and energy can flow in Either direction.
Models are available in a variety of configurations with current ranges up to 1000A and nominal voltage ratings up to 600V. Models are available in 1, 2 and 3 element versions; suitable for all single-phase and three-phase power systems. RS485, CAN BUS, Modbus and Analog output signals are available. Forward (consumed) power is indicated with a positive polarity and reverse (generated) power with a negative polarity. Unidirectional outputs (4-20mA) indicate forward (consumed) power, 4-12-20mA allow for both directions. Easy scaling of VTs and CTs is possible. All outputs are galvanically isolated from the measured inputs and instrument power.
The UFIX-3ph sensor power input is designed to operate over a wide range associated with process control and sub-station auxiliary dc supply systems. Some typical applications are voltage monitoring in Solar PV, Dc drives, UPS, Frequency Changers, Process Control, Rail Transportation, and EV. For all products, a NIST/NPL/UKAS traceable calibration certificates of conformance are available.
The UFIX-3ph fast-response capability is aligned to control systems for renewable energy sources found in Microgrids. A Microgrid is a group of interconnected loads and distributed energy sources that acts as a single controllable entity with respect to the grid. It can monitor connection/disconnection from the grid allowing operation in grid-connected or island mode - improving the utilisation of available energy and capturing short-term energy bursts previously lost or discarded
