Triol AK06 - *** - 2
Variable speed drive with an active rectifier for electric submersible pumps. The drive series is made in compliance with Directive 2006/95/ЕС «Low Voltage Directives» and Directive 2004/108/ЕС «Electromagnetic Compatibility».
Purpose
The design of the Triol AK06-***-2 with active rectifier is in compliance with EC standards.
Triol AK with active rectifier is intended to control and protect electric submersible pumping units (ESPU) with a nominal power from 50 to 200 kW. The Triol AK06 with active rectifier provides open-loop scalar control (V/f control) for induction (asynchronous) motors and sensorless control for brushless DC motors.
Main features:
The Triol AK06-***-2 is specially designed to consume the sinusoidal current with a total harmonic distortion less than 5%. This makes the drive network friendly, reducing voltage harmonic distortion in the network, which protects sensitive equipment connected to the same supply.
The Triol AK06-***-2 has a power factor of more than 98%, as the power consumed is nearly active.
When the motor is braking, excess power is fed back to the network.
The input EMC filter reduces the radio frequency harmonics generated to the network.

The Triol AK06-***-2 offers the following functions:
- Soft start and stop of the motor with preset acceleration and braking rate (Hz/s);
- “Manual”, “Automatic” or “Automatic with preset time” modes determine whether the motor starts automatically after a fault occurs or awaits the operator’s command;
- “Current optimization” mode changes the output voltage to get the minimum full load current at fixed output frequency;
- Start and stop according to a preset time configuration;
- Local and distant operating parameter control;
- Change output frequency according to a preset time configuration;
- Operating the motor in field weakening region by raising the output frequency above nominal;
- Starting ESP after supply is delivered after a preset time;
- Maintaining a preset technological parameter (pressure, current, vibration);
- Starting ESP in “swinging” mode; “kick start swinging” mode can be used to unblock ESP in the case of mechanical jamming;
- “Soft start with synchronization” holds a frequency for a preset time upon starting and then continues to start operation;
- Starting ESP in the “unjamming” mode delivers maximum torque at low frequency;
- Continuous monitoring of ESP isolation resistance and turning the motor off when isolation drops under a certain preset value;
The Triol AK06-***-2 protects ESPs from the following:
- Short circuit current;
- Underload;
- Overload;
- Low “cable – ESP chassis” insulation resistance;
- High ESP temperature (with submersible telemetry);
- Low base oil pressure (using submersible telemetry);
- High vibration level (using submersible telemetry);
- High pipeline pressure (using contact pressure gauge);
- ESM current unbalance; and
- Start while turbine rotation is present.
