Frequency Regulation

The production, transformation, transmission, distribution and consumption of electricity is one continuous process. The change of the load, i.e. the level of energy consumption, should cause a corresponding change in the level of generated energy. It means that the power system should be a balance of produced and consumed energy, taking into account technological cost of conversion, transmission and distribution. Otherwise, electric power quality indicators will be violated. For example, at infringement of balance of active power the frequency in the grid will have a value different from 50 Hz. One of the automatic devices on the lowest rung in the hierarchy of automatic dispatcher control system of frequency and power interchange is the system of automatic control of power units (SACPU). It is a comprehensive and complex device, which consists of several connected together simpler systems, governing all thermal power devices of a power unit. SACPU ought to regulate the active power of the unit and participate in primary frequency regulation in the network with a given accuracy and sensitivity; also, it ought to be adequately fast. At the same time, this device should be simple from the point of view of technical implementation, easy to use, allow one to maintain a high level of efficiency, reliability, durability and environmental performance of the units. To satisfy all these requirements (often conflicting) simultaneously, SACPU should have a certain structure, which depends on the composition and characteristics of heat power equipment of the power unit and on operating modes. The analysis of known SACPU have demonstrated that they are unable to fully provide the requirements of the modern standards for quality control of frequency and power, i.e. the SACPU models are still in need of structural and parametric optimization on the basis of the proximate methods developed at the Belarusian National Technical University.

The article is concerned with the advanced automatic control system of electrode positioning at electric arc steel making furnaces and ladle furnaces. Analysis of structure of modern electrode positioning control systems’ nonlinear controllers for electric arc furnaces and ladle furnaces is considered. Disadvantages of these systems were analyzed. A control system with a conventional structure from well-established foreign suppliers was compared with the advanced automatic control system of electrode positioning.
