چکیده مقاله :
كنترل توان اكتيو عبوری از خطوط انتقال به‌خصوص در شرايط تراکم یا وقوع خطا يكي از مهم‌ترين مسایل پيش رو در کنترل و مديريت صحيح سيستمهاي قدرت است. در اين شرايط براي كنترل پيوسته و به‌خصوص افزايش توان انتقالي، عمدتاً از خازن سري كنترل‌شونده با تريستور (TCSC) استفاده مي‌شود كه در واقع به‌علت قابليت سريع كنترل تريستورها و توانايي در پايدار نگه‌داشتن سيستم حين بروز خطاهاي متفاوت مي‌باشد. در اين مقاله به كنترل توان اكتيو انتقالي در محدوده تقريباً 10 مگاواتي به كمك TCSCپرداخته شده است. براي كنترل زاويه آتش TCSC از كنترل‌كننده‌هاي مختلف اعم از كنترل‌كننده PID، فازي و ANFIS استفاده شده و با توجه به نتايج حاصل از شبيه‌سازي، مزايا و معايب هر يك از اين كنترل‌كننده‌ها بررسي شده است. كنترل‌كننده ANFIS نيز به‌صورت حلقه‌باز پياده‌سازي شده و داراي پاسخ گذراي بسيار مناسبي است. عيب اين نوع پياده‌سازي خطاي حالت ماندگار آن بوده و نسبت به تغيير پارامترها نيز بسيار حساس مي‌باشد. لذا براي رفع اين مشكلات مي‌توان آن را با كنترل‌كننده فازي طراحي‌شده تركيب كرد و در عين سادگي، عملكرد بسيار مناسبي از مجموعه به‌دست آورد.
Control of transmitted active power is an important issue in operation and management of power systems especially in congestion or fault conditions. In these situations, Thyristor Controlled Series Capacitor (TCSC) is used to continuous control and increase the transmitted power due to these facts that TCSC can act dynamically and is able to stable the system during fault conditions. In this paper, the transmitted power is controlled in the ten megawatt span by using the TCSC. For this purpose, various controllers such as PID, fuzzy and Adaptive Network-based Fuzzy Interface System (ANFIS) are designed to continuous control of the transmitted power. Simulation results evaluate advantages and disadvantages these controllers. ANFIS controller is designed by open loop method which has a good transient response. However, it has a large steady state error and is very sensitive to the variations in system. Fuzzy and ANFIS controllers are combined to remove these defects. The simulation results verify the advantages of the fuzzy-ANFIS controller with respect to the other designed controllers.
