When the first power systems were introduced more than a hundred years ago the controls used were very primitive and undeveloped. These systems were usually rather small, and the requirements regarding quality and stability were not as high as they are today, so the control could be performed manually in most cases. Fairly soon the end users started to put higher demands on the quality of supply, that is, on the voltage profile and the frequency, so optimized automatic controllers and regulators had to be introduced to meet these requirements.
One of the main power control systems is the Automatic Voltage Regulator (AVR) system. The role of an AVR is to force the generator terminal voltage to be at a specified level via the excitation system, and is to control the reactive power flow. However, the stability would seriously influence the security of the power system. Hence the designed controller of the AVR system should be robust to load change.
Design of optimal controllers is a crucial point and obviously a fundamental aspect in optimization of system global performances. Tuning of a proportional integral derivative (PID) controller is investigated. Indeed, it is well known that such controllers are the most used controllers in industry. This is mainly due to two major advantages:
In this program, we propose to implement a metaheuristic particle swarm optimization (PSO) algorithm, first introduced by Kennedy and Eberhart, in order to evaluate the PSO-PID performance criteria in time and frequency domain applied to the AVR system. Compared to this traditional approach, the use of this design method allows optimization and tuning of controllers. Indeed, initial specifications expressed, for instance, in terms of time responses, maximum overshoot or control energy corresponding to functions that can only be computed using simulation. Thus, PSO which only requires the possibility of evaluating cost and constraint functions appears as a good candidate method.
From an optimization point of view, some attempts to optimize these difficult cost functions have been performed, but the proposed method remains a local search method and so is strongly dependent on the initial point. Metaheuristic PSO methods, with the different topologies, will also be tested to solve the controller tuning and optimization problem.
The main aim of this program is to make the participants familiar with the excitation systems for synchronous generators in industrial applications. This specialist knowledge enables the participants evaluating specifications, understanding various acceptance tests, and setting up a maintenance plan. In addition, the participants can investigate and solve malfunctions or provide your repair shop with an accurate and detailed description of malfunctions.
Upon the successful completion of this course, participants will be able to:-
This program is excellent for training technicians, operators and engineers as well as for the multi-craft training needs of process and manufacturing facilities.
