Reducing the overspeed during load rejection would benefit the mechanical and hydraulic systems in a hydropower station. This paper presents some selected results of a pilot installation of a dynamic braking system. The 4 MW dump load was installed and tested on a 10 MW Francis turbine unit. The results show that the overspeed reduction is obtained and compares well with simulation results. Further, a reduction in vibration levels is positive as well as the reduced time for stopping and possible resynchronization. It is argued that a similar system with continuous cooling could be used as an attractive alternative to spillway capacity.

“…There are studies examining the use of braking resistors jointly with other devices to increase its efficiency [4][5][6], and we think that there are possibilities of their use for achieving an even better transient stability. Some examples of practical applications of braking resistors can be found in the Bonneville Power Plant (Oregon) [1], Four Corner Power Plant of Public Service Company (Arizona) [1][2][3], and in Owase Mita and Atsumi power plants of Chubu Electric Power Co. (Japan).…”

SUMMARYThe electric power industry has undergone considerable changes in the past decade throughout the world. The essential feature of these changes is to promote competition among utilities and to form active power market with reliable and less expensive electricity. Under these circumstances, stabilization and voltage stability problems of power systems are very important. Power systems engineers are examining the effect of the resistance value of braking resistors and the timing of their insertion on the improvement of the stability level.In this paper, we report on experiments carried out on the optimal size and switching of braking resistors, shunt capacitors, and other auxiliary devices. The experimental system model consists of a single synchronous generator connected through two parallel transmission lines to an infinite bus.

“…One of the most important stability problems is the inter-area oscillations between the interconnected electric systems [2][3][4] [5]. This phenomenon usually involves two groups of generators in two different areas or subsystems that swing against each other, and since a large number of generators and related equipments are involved, it has serious impacts on power system operations.…”

Understanding the mechanism of inter-area oscillation is an important problem in power system stability research. In this paper, by introducing periodic disturbance, we propose a new mechanism to model inter-area oscillation caused , which promises new direction in this field. As a proof of our idea, a two-machine equivalent model based representation of two interconnected power systems was used. Chaos and bifurcation phenomena have been detected in the system by using a special Poincare section method that considers long-term characteristics of the sampled signal. Based on simulation study of the proposed model, inter-area oscillation evolving from period doubling bifurcation to chaos can be unfolded as the disturbance parameter increases. Our simulation results show three oscillation patterns; those are intermittent oscillation, transient chaos and chaotic oscillation. These results can give new ideas to interpret abnormal oscillating phenomena that happen in real power systems.
