A 2km section of the Dukhan South Service Road (DSSR
) will be closed for one year and the traffic to the Dukhan North Service Road between the Temporary Truck Route and the Dehailiyat Interchange would be diverted from November 18.
DSSR is a newly proposed concept originated from N1 security guideline [1, 2].
Although some TSC results can be used as the points of DSSR boundary , TSC fails to describe the integrated boundary.
Author of  made attempt to present a simplified model and approach of security assessment with the concept of DSSR. But the papers exposed 2 main defects: (1) only the load of substation transformers and their rated capacities are formulated, which provide relatively limited information on the system status; (2) feeder contingency and maintenance are ignored although feeder contingency occurs much more frequently than transformer contingency.
"In combination with RE/Locate," continues Stein, "the DSSR
system is a potent tool.
Section 2 presents the DSSR's fundamental characteristics and its equivalent circuit models.
Figure 1 presents the proposed microstrip DSSR. Two square slots (D x D) are connected with a rectangle slot (G x W) on the top plane.
For the given DSSR dimensions of D = 4.5, G = 0.4, [P.sub.1] = 1.5, [P.sub.2] = 0.7, and W = 1.56 mm, [C.sub.DSSR] and [C.sub.P] are calculated as 0.014 pF and 0.72 pF, respectively.
