(6) Repeat steps 2~5 until the length of one principal tie line
is zero, and the corresponding pressure at this time is MMP
The above equation gives the tie line
power between area 1 to 2.If any deviation in the angle and the tie line
power changes with the amount i.e.
The optimized FOPID controller minimizes the frequency and tie line
deviations faster as compared to tuned PID controller.
Figure 7 shows the active power oscilloscope record of the second Long-Dou tie line
during the power oscillation.
The power system investigated in this work contains three area thermal power systems interconnected through the tie line
as shown in Figure 1.
The phase volume ratio, [PHI], can be estimated from the triangular phase diagram by the tie line
and lever rule (11), as shown in Fig.
The various frequency deviations and tie line
power deviations in thermal area 1 and hydro area 3 without presence of GRC are shown in the figures.
Plant Integration Associates Inc., in Port Chester, will provide turnkey installation of a tray sortation system, from the last strapper on each tie line
to the truck loaders.
At a user level, or system level, the gateway should function like a PBX tie line
or digital trunk.
"Each tie line
has a stacker, a three-quarter-wrap labeler, a cross-tying system, a cross over belt and a telescoping truck loader," King said.
