3-Bus System (System I)

I. Introduction:

$$\bullet$$ This system has 3-phase (3$$\phi$$) fault at the midpoint of each line, as shown in the figure given below.
$$\bullet$$ It is considered as a one of the most popular test cases in the relays coordination problems. It is the first selected system used in the first puplished paper [1] in the literature.
$$\bullet$$ The plug-setting ($$PS$$) is considered discrete in uniform steps of 0.5 A, while the time-multiplier setting ($$TMS$$) is considered continuous. The coordination time interval ($$CTI$$) is equal to 0.2 s. The researcher can change these settings to get fair comparsion with other conducted studies in the literature.
$$\bullet$$ In this test case, the transient selectivity constraints are considered too. All the CT ratios ($$CTR$$), the listed P/B relay pairs, the 3$$\phi$$ fault at the middle of each line, the generator and line data and the variable bounds of the relays settings are given below (click on them for bigger size):

II. Single-Line Diagram:

$$\bullet$$ This single-line diagram was drawn by Ali R. Alroomi in Dec. 2013 and all the necessary data were coded in MATLAB m-files.
