A method of solving surge tank problems with an electronic digital computer is presented in this thesis. The basic differential equations governing the transient behavior of the water mass in a surge tank system are developed in dimensionless form. A program prepared for the ALWAC III E computer at the University of British Columbia, solves these equations by a numerical integration process of the Runge-Kutta type.
This program is suitable for the solution of a wide range of surge tank problems involving a single surge tank either upstream or downstream of the power unit in a hydroelectric installation. Solutions for the three basic types of surge tanks (simple, restricted orifice, or differential tank) under any of the three conditions for turbine discharge (flow, gate or power variation) are possible. The surge tank geometry and system coefficients may be altered to suit any particular circumstance. Also, the program contains a procedure which allows the incorporation of a variable turbine efficiency term in the calculations. Several numerical examples are included to illustrate the use of this program.
