Course content

The course is given next time Spring2018. The course is presenting the structure matrix method for mathematical modeling of hydro-electric power plants and pump systems connected to complicated pipelines-and/or tunnel systems included valves, accumelators and control systems. The theory are founded on nonlinear friction alleviation of oscillating flow through tunnels and pipelines and the effects of turbines- and pump characteristics in system for turbines and pumped-storage power plants or in pump systems. Frequency response measurement methods to decide the stability are being described. Mathematical modeling of tunnels, pipelines, turbines, water level regulation, generators and electric grid in the frequency domain are being described.

This course will not be held if less than 5 students are signed up.
