Table 5 Estimation error of frequency and rate of frequency change with different lengths of the line
From: Protection and control of microgrids using dynamic state estimation
Line length | Frequency error | dFreq/dt error |
|---|---|---|
1.5 miles | −6.513 × 10−5~1.77 × 10−4Hz | −1.144 × 10−3~1.049 × 10−3Hz/s |
2.5 miles | −9.464 × 10−5~2.82 × 10−4Hz | −1.906 × 10−3~1.689 × 10−3Hz/s |
4 miles | −1.29 × 10−4~4.51 × 10−4Hz | −2.896 × 10−3~2.751 × 10−3Hz/s |
