Triol has successfully completed a three-day technical training program at the facilities of Türkiye Petrolleri A.O., focused on the Oil production variable speed drive AK06 UD.
The training was delivered by @Rizky Wiguna and brought together nearly 80 participants over three days — engineers, operators, and technical specialists working directly with artificial lift systems. The sessions were conducted on live equipment, ensuring full alignment between theory and real operational practice.
Training Scope: AK06 UD in Detail
The program was built around the Oil production variable speed drive AK06 UD platform and covered both system fundamentals and advanced functionality.
1. VSD Fundamentals and Architecture
- Participants reviewed:
- Converter (6-pulse rectifier) operation
- DC bus behavior and ripple control
- Inverter switching logic and PWM principles
- V/Hz control strategy
- Built-in sine wave filter performance (THD ≤ 5%)
Special attention was given to how the sine wave filter reduces dU/dt stress, protects step-up transformers and ESP motors, and minimizes harmonic distortion.
2. Cabinet Design and Internal Components
Hands-on inspection of AK06 UD cabinets included:
Rectifier and inverter units
- DC-link choke
- UMKA07 controller
- Electronic panel and protection systems
- Sine wave filter reactor
- Cooling system (air-to-air, no liquid cooling)
- Integrated protection circuits and circuit breakers
Participants analyzed how the sealed enclosure design supports reliable operation in harsh environments, including high ambient temperatures up to +60°C.
3. Advanced Start Modes for ESP Applications
A major focus was placed on ESP-oriented startup algorithms:
- Soft Start
- Start with Synchronization
- Jogging (Kick Start)
- Swinging (Reversible Rotation Start)
- Unblocking Mode (maximum torque at low frequency)
- Hard Start
Practical cases demonstrated how these modes help:
- Deblock stuck ESPs
- Reduce mechanical stress
- Prevent unnecessary round trips
- Maintain stable well operation
4. Operational Modes and Process Control
The training covered key AK06 UD control capabilities:
- Manual / Automatic operation
- Program mode (step frequency ramping)
- Current regulator
- PID-based non-technological parameter control (pressure control example)
- Timer-based operation
- Shaking mode (deposit reduction)
- Gas bag remove algorithm (automatic gas lock detection and recovery)
- Catch-on-the-fly functionality for backspin conditions
Real-case simulations showed how these features improve well stability, protect equipment, and reduce downtime.
Why On-Site Training Matters
Training on drives significantly enhances learning outcomes. Engineers work with real cabinet layouts, real parameter sets, and real operational scenarios including backspin, gas lock, and synchronization cases.
The result:
- Better parameter optimization
- Faster fault diagnostics
- Improved ESP protection
- Higher operational confidence
We appreciate the strong engagement and professional organization by the team at Türkiye Petrolleri A.O. The scale of participation reflects a serious approach to technical excellence and production reliability.
