Một hệ thống relaying định hướng chỉ với một đầu cho đường truyền tải hai mạch sử dụng hệ thống chuyên gia mờ
Tóm tắt
Các lỗi xảy ra ở các đoạn khác nhau rất khó để xác định bằng các kỹ thuật truyền thống. Bài báo này nghiên cứu một hệ thống chuyên gia mờ cho relaying định hướng, phân loại và xác định vị trí của các lỗi trong các đường dây truyền tải hai mạch. Các giá trị dòng điện đo được chỉ ở một đầu của đường dây truyền tải hai mạch được sử dụng để tính toán các hệ số Fourier rời rạc. Do đó, sơ đồ này không liên quan đến bất kỳ kênh truyền thông nào. Hệ thống chuyên gia mờ được trình bày đạt được từ cấu trúc của hệ thống MAMDANI trong phần mềm LabVIEW. Các nghiên cứu trường hợp thử nghiệm cho thấy hiệu quả của sơ đồ đã trình bày. Kết quả mô phỏng xác nhận rằng việc relaying định hướng, phân loại và ước lượng vị trí là rất chính xác. Sơ đồ này có khả năng thích ứng với sự thay đổi của vị trí lỗi, điện trở lỗi, góc khởi phát lỗi và loại lỗi.
