ABB’s solution provides high precision control functions and ensures high operational reliability:
- Characteristic curve: deviation of ≤ 0,5 %
- Ambient temperature effect: ≤ 0.5 % per 10 K
- Influence of vibration: ≤ 1 % to 10 g and 80 Hz
The positioners have a special function in the automatic adjustment of the parameters.
Additionally, the control parameters can be set automatically in adaptive control mode (“Adaptive mode”). With this feature, internal control parameters are dynamically adjusted. This ensures that if external operating conditions change, the control parameters are automatically modified to maintain stable actuator positioning.
Overall, we installed 70 positioners at each of the customer's three production sites, resulting in the total of 210 new TZIDC positioners at the power plant.
It seems that the best summary of this project, and proof of our success, is the customer's comment:
“When it comes to valve controller applications at the Çatalağzı power plant, Eren Enerji trusts ABB positioners above all.”
