One of the most powerful features of TurboWatch system is its open and flexible analysis engine. All analysis models and equations can be easily viewed and modified by end users in a word processor like editor without the use of any programming or scripting language. The flexibility and ease of use of TurboWatch analysis module combined with it’s custom libraries, specialized analysis functions, data collection, filtering and reporting tools, makes it a powerful tool that can be tailored for the most complex analysis tasks.
Customized Analysis Models
Performance analysis models are customized for individual machines to be monitored. TurboWatch uses thermodynamic and statistical modeling to compute key performance indicators (KPI) such as component and overall efficiencies and fouling factors.
Extension libraries are provided for specialized analysis functions. Numerical techniques are used to compute expected values from available performance curves for a machine and the deviations from expected value serve as a measure of degradation or indicator of fault. Empirical equations of state models are used for computing gas properties used in computing performance of gas compressors and turbo-expanders.
Continuous Online Analysis
The Online Analysis Service performs continuous unattended analysis at pre-configured periodic intervals. It computes performance parameters for entire machine as well as individual equipment sections and analyzes new incoming data in background mode. All results are checked against validity and alarm limits and saved to the database for historical trending.
Interactive Offline Analysis
An interactive utility allows users the ability to do on demand or offline analysis. This program allows plant engineers to modify existing models or add new analysis models and equations and run what-if scenarios.
