LỜI MỞ ĐẦU

Trong thời kì khoa học và kĩ thuật đang từng bước phát triển mạnh, việc xây

dựng các toà nhà cao sở, trung tâm thương mại, khách sạn,… ngày càng trở nên

hiện đại, tiện nghi để phục vụ các nhu cầu cần thiết của con người. Trong đó, việc

thiết kế và cung cấp điện là vấn đề không thể thiếu, hệ thống cơ điện của tòa nhà vì

thế cũng ngày một hiện đại hóa, các thiết bị thông minh được sử dụng nhiều hơn, phần cơ điện cũng cần có sự đổi mới, có những cách nhìn nhận vấn đề cơ sở thiết kế

khắt khe hơn. Một phương án cung cấp điện tối ưu sẽ giảm được chi phí đầu tư

đáng kể cho hệ thống điện, hơn nữa còn giảm tổn thất điện năng, đảm bảo an toàn

khi sử dụng và thuận tiện khi sửa chữa.

Từ những lí do trên em chọn đề tài: Thiết kế cung cấp điện phần cơ cho công

trình “Tòa nhà hỗn hợp, trụ sở công ty – tòa nhà Detech Mỹ Đình” để nghiên cứu

và hiểu sâu hơn về hệ thống cấp nguồn cần thiết trong một công trình cao tầng.

Em đã thực hiện đồ án náy dưới sự hướng dẫn tận tình của cô Nguyễn Thị

Phượng nhưng do trình độ kiến thức còn nhiều hạn chế nên có đôi phần thiếu sót.

Em rất mong nhận được sự đóng góp ý kiến, phê bình và sửa chữa từ quý thầy cô và

các bạn sinh viên để đồ án này hoàn thiện hơn.

Em xin chân thành cảm ơn!

Hà Nội, ngày… tháng … năm……
