Purpose
control, monitoring of parameters and protection of SRP/PCP electric motors with power ranging from 5 to 75 kW, with smooth acceleration, deceleration and speed control.
The product provides the following:
- manual or automatic control
- motor smooth acceleration and deceleration
- energy saving
- motor rotor speed control
- rocking start to overcome jamming (heavy start)
- continuous control of the mains voltage, phase sequence, values of the currents in three phases
- calculation of voltage and current imbalance, power factor, load factor, power consumption, operating time
- registration of monitored parameters and reasons for shutdown in real time with saving records in case of power failure
- minimization of emergency shutdowns and increase in flow rate due to automatic control of rotation frequency
- protection of equipment from emergency caused by failures in the electric mains and sucker rod pump unit
- automatic reclosure when parameters return to the operating range
The drive provides connectivity to the following equipment:
- remote control systems (normally closed and normally open contacts)
- the SCADA-system by means of RS-232 or RS-485 interface via the Modbus-RTU exchange protocol
- GPRS modem with the ability to upload information to the Internet
- wireless or wired dynamograph
- wellhead fluid temperature sensor
- motor temperature and vibration sensor
Options
- integration of an input filter or an active front end to ensure the input voltage and current waveform distortion factor to be not more than 5% in accordance with IEEE-519-2014
- ability to display graphs and dynamometer charts
- ability to create dynamometer charts without dynamographs
- compatibility with cavity pumps
- smart control algorithms: calculation of the pump fill factor, flow rate, loads on downhole and surface equipment, automatic adjustment for max flow rate, reduction of plunger-liquid impacts
- ability to manufacture drives with IP66 enclosure protection class
Advantages
- ability to change the rocking frequency without replacement of pulleys and shutdown
- compatible with downhole monitoring (thermo-manometric) systems produced by various manufacturers
- ability to connect a dynamograph
- ability to save history to a USB-drive
- graphic liquid crystal display
- software update without shutting down the pumping unit
- archive of dynamometer charts with the number of records up to 500
- compliance with the requirements of oil companies and GOST R51321.1-2007
- ability to include in the drive a set of electricity metering devices included in the State Register of Measuring Instruments
