This paper examines the torsional stresses and life expectancy that occur on600 MW turbine-generator shafts of Piagwei power plant due to various reclosing of transmission line after faults in different system operation conditions.
The natural gas transmission line, extending 4,000 km, will span nine provinces (autonomous regions and municipality) from west to east.
That caused safety systems to malfunction, and transmission lines and then a power station to shut down.
Such big plants are harder to finance than small photovoltaic installations, and require more planning permissions and infrastructure, such as transmission lines. But they produce a lot of power.
Another high-current application that has been proposed is lossless power transmission lines, which can carry much higher current densities than nonsuperconducting ones.
