Trong quá trình vận hành hệ thống điện, không phải lúc nào hệ thống cũng hoạt động ổn định, thực tế chúng ta ln gặp tình trạng làm việc khơng bình thường hoặc sự cố như ngắn mạch, quá tải. Nguyên nhân có thể do chủ quan hoặc khách quan. Hệ thống bảo vệ Rơle sẽ phát hiện các tình trạng đó để đề ra những biện pháp xử lý kịp thời. Hiện nay với sự phát triển của khoa học kỹ thuật, thiết bị bảo vệ rơle ngày càng hiện đại, nhiều chức năng và tác động chính xác hơn.Ở nước ta hiện nay, xu hướng sử dụng rơle kỹ thuật số để dần thay thế cho các rơle điện cơ đang được xúc tiến mạnh mẽ.
<i>Luận văn “ Thiết kế hệ thống bảo vệ rơle cho trạm biến áp 110 kV” được trình </i>
bày trong 5 chương:
- Chương 1: Mô tả đối tượng được bảo vệ và các thơng số chính - Chương 2: Tính tốn ngắn mạch phục vụ bảo vệ rơle
- Chương 3: Lựa chọn phương thức bảo vệ
- Chương 4: Giới thiệu tính năng và thông số rơle được chọn
- Chương 5: Tính tốn các thơng số và kiểm tra sự làm việc của bảo vệ Để hoàn thành luận văn này, em xin chân thành cảm ơn sự hướng dẫn, chỉ bảo tận tình của Cơ Ths. Phan Thị Hạnh Trinh, bộ môn hệ thống điện- trường Đại Học Cơng Nghiệp Thành Phố Hồ Chí Minh . Xin chân thành cảm ơn các anh đi trước cũng như các bạn đã có những đóng góp ý kiến quý báu giúp đỡ em trong quá trình hồn thiện Luận văn này. Tuy nhiên, do thời gian có hạn, vấn đề nghiên cứu có liên quan đến nhiều lĩnh vực và vốn hiểu biết chưa nhiều nên chắc chắn luận văn có nhiều thiếu sót. Em rất mong nhận được sự nhận xét cũng như góp ý của q Thầy Cơ để luận văn của em hồn thiện hơn.
Em xin chân thành cảm ơn.

<b>CHƯƠNG 2: TÍNH TỐN NGẮN MẠCH PHỤC VỤ BẢO VỆ RƠLE </b>
<b>2.1.Mục đích tính tốn ngắn mạch </b>
Tính tốn ngắn mạch tại các vị trí trên sơ đồ nhằm tìm ra dịng ngắn mạch max và min đi qua các vị trí đặt bảo vệ, phục vụ cho việc chỉnh đỉnh và kiểm tra sự làm việc của các bảo vệ. Để tìm ra dịng ngắn mạch chạy qua các BI phục vụ cho bảo, ta xét hai chế độ.
Nếu tính tốn ngắn mạch theo cách bình thường thì chúng ta phải tính tốn hết những giá trị ngắn mạch trong những trường hợp sau:
<b>2.2.Xét điểm tính tốn ngắn mạch </b>
Xét trạm ta dùng bảo vệ so lệch làm bảo vệ chính và bảo vệ quá dòng, bảo vệ chống chạm đất làm bảo vệ dự phòng
Đối với bảo vệ so lệch (87)
Để cài đặt dòng khởi động bảo vệ so lệch được dựa trên dòng ngắn mạch lớn nhất ngoài vùng bảo vệ ( I ngắn mạch 3 pha).

<b>2.3.Các giả thiết cơ bản để tính ngắn mạch </b>
Để thiết lập sơ đồ tính tốn ngắn mạch, ta sử dụng một số giả thiết liên quan tới thành lập sơ đồ thay thế tính tốn ngắn mạch như sau:
Tần số của hệ thống không thay đổi . Bỏ qua phụ tải khi tính tốn ngắn mạch.
Mạch từ khơng bị bão hịa. Khi đó mạch điện chỉ phi tuyến nên có thể áp dụng nguyên lý xếp chồng trong tính tốn.
Bỏ qua các đại lượng nhỏ trong thông số của một số phần tử:
Hệ thống có sức điện động ba pha đối xứng.
Các tính tốn thực hiện trong hệ đơn vị tương đối định MBA.
