摘要

The objective of the project has been, based on a review of the existing main types of distribution stations prevailing in Estonia, to carry out a basic design of 2 to 3 standard stations with different capacities as a part in a modernization programme. The objectives have been met as follows: Based on the document review of the existing main types of stations in Estonia the operating parameters were outlined for four types of stations: Basic design concepts for district regulator stations cover 2 low pressure district regulator stations of the following capacities: 6/0.020 bar cabinet type regulator station with a max. flow rate of 200 Nm(sup 3)/h; 3/0.020 bar regulator station with a max. flow rate of 1,000 Nm(sup 3)/h.
