Abstract

A control system for turbine systems configured to provide accurate interpretations of detected particle accumulation, improve performance of turbine systems, and/or minimize costs due to downtime and maintenance are disclosed. The control system may build an intelligent model of fluid flow based on measured data provided by a sensor in a fluid flow path of the turbine system. The intelligent model consults a filter efficiency framework and determines an impact value that quantifies an operational efficiency of the turbine system and may identify a location of possible leakage, estimate a total amount of ingress of particles, identify components of the turbine system that may be operating in a diminished capacity, estimate a risk of damage to components of the turbine system, and/or recommend mitigation actions.

Dependent claims

A system for assessing the efficiency and integrity of an inlet filtration system of a turbine, the system comprising:

one or more sensors operative to generate at least one measured data value of air intake particles within a fluid flow path of the turbine;
a controller in electronic communication with one or more sensors and operative to:
utilize an intelligent model to process the at least one measured data value, the intelligent model consulting a filter efficiency framework,
wherein the system for assessing the efficiency and integrity of an inlet filtration system of a turbine is configured to use the filter efficiency framework to relate the at least one data value of the air intake particles to a filter efficiency of the air filtration system of the turbine,
wherein the system for assessing the efficiency and integrity of an inlet filtration system of a turbine is configured to use the filter efficiency framework to identify a location of possible leakage in the system for assessing the efficiency and integrity of an inlet filtration system of a turbine,
wherein the controller is configured to compare the location of possible leakage in the system for assessing the efficiency and integrity of an inlet filtration system of a turbine with an offline computational fluid dynamic evaluation to estimate a risk of further damage to at least one component of the system,
wherein the controller is configured to determine a dirt load estimate based on a particulate concentration multiplied by a rate of air flow multiplied by a number of hours of operation,
wherein the intelligent model is configured to utilize the filter efficiency framework to determine one or more of a forecast degradation, a fouling rate, and/or an erosion rate.

A method of quantifying an effect of continued fluid flow within an air filtration assembly of a turbine system, the method comprising:

consulting an intelligent model of fluid flow tailored to the turbine system;
determining an impact value using the intelligent model of fluid flow based on at least one detected data value of an air intake particle traveling through a fluid flow path of the turbine system;
determining a location of a possible leakage in the system using the intelligent model of fluid flow;
calculating a key performance indicator from the impact value;
