| چکیده | ||
| در این پژوهش، به منظور شبیه‌سازی اثرات رسوبگذاری و فرسایش پره‌های کمپرسور توربین گاز V94.2، یک مدل ترمودینامیکی توسعه داده شده است. رویکرد نوین این مطالعه شامل در نظر گرفتن اثرات دما و رطوبت محیط بر عملکرد یک توربین دارای عیب و استفاده از سیستم کنترلی توربین در شرایط بار کامل است که به آن کنترل دمای خروجی یا OTC گفته می‌شود. در این رویکرد، از ثابت نگه داشتن دمای اصلاح شده‌ی خروجی توربین استفاده می‌گردد تا دمای ورودی به توربین در یک بازه ی ایمن برای پره‌ها نگه داشته شود. این مدل توسط داده‌های واقعی یک توربین گازی صحت سنجی گردیده‌است. نتایج نشان می‌دهد که می توان با تغییر نقطه تنظیم کنترلی OTC و با در نظر گرفتن دمای ورودی به توربین، مقداری از افت‌ها را جبران نمود. نتایج بیان می‌کند که رسوبگذاری، پارامترهای توان تولیدی، دمای ورودی به توربین و بازدهی توربین گازی را بیشتر از فرسایش پره‌ها کاهش می‌دهد. همچنین انحراف از عملکرد سالم، با شرایط محیطی تغییر می‌کند. نتایج نشان می‌دهد که با افزایش 6 درجه‌ای نقطه تنظیم سیستم کنترل یک توربین معیوب، می‌توان با توجه به دمای محیط، توان را تا 1% و دمای ورودی به توربین را تا 8/0% افزایش داد. | ||

| چکیده [English] | ||
| In this research, a thermodynamic model has been developed to simulate the effects of fouling and erosion of the compressor blades of a V94.2 gas turbine. The novel approach of this study involves considering the influence of ambient temperature and humidity on the performance of a faulty turbine as well as using the turbine control system under full load conditions, referred to as Outlet Temperature Control (OTC). In this approach, maintaining a corrected turbine outlet temperature is employed to keep the turbine inlet temperature within a safe range for the blades. This model has been validated using real-world data of a gas turbine. The results demonstrate that by adjusting the OTC control setpoint and taking into account the turbine inlet temperature, a portion of the performance losses can be compensated for. The findings indicate that compressor fouling has a greater impact on parameters such as power output, turbine inlet temperature, and gas turbine efficiency compared to blade erosion. Furthermore, deviation from healthy performance varies with environmental conditions. The results also show that by increasing the control setpoint of a degraded turbine by 6 degrees, considering ambient temperature, power can be increased by 1%, and turbine inlet temperature can be increased by 0.8%. | ||
