fluctuations are challenging part of plant operation. Process oscillations with high variance are beyond noise and should have causal reasons. DCS trends and plant data embed signatures of these disturbed variables. Observing plant wide oscillations and their systematic mitigation amply contributes to reduced variability and improved KPI averages. Automated AKXA tool uses trends to show plant wide Non-Linearity Index, correlates oscillations in frequency domain and establishes possible sources. Supports technical team in predictive & preventive operation, fault diagnosis and process optimization.
OPTIMakx-NLA
Algorithm based systematic assessment / diagnosis of process oscillations across plant.
Technical Features
Offline Data Read : Automatically reads recent trends for pre-defined set of crucial process variables from plant DCS (Historian) for required date/time period – on demand or as scheduled task.
Data Health Index : detects and highlights bad, missing, outlier data. Generates single Data Health Index to show confidence for further usage.
Oscillations Assessment : advanced variance analysis on process variables, checks for noise (random uncontrollable disturbances), analysis for variable frequencies, correlates oscillations and detects lead-lags for cascading effect. several KPIs including Non-Linearity Index, CoV, % deviation, FrequencyIndex -etc – graphical summary of overall NL Index for section/equipment wise groups of process variables /section /department /plant performance.
Oscillations Diagnosis : Advanced analytics like classification of reasons based on NL Index, diagnosis for controller tuning issues, control valve / damper abnormalities, support equipment saturation issues, external disturbances and more… – based on scientifically proven algorithms.
Powerful Visualization : Innovative and User friendly graphical display of results which can be summarized and customized based on relevance at different levels (Chief/Manager/HoD/Engineer/Supervisor..) and different groups (plant, unit, section, equipment…).
