The article deals with the basic methods of stabilizing voltage generators for small hydroelectric power plants. It shows a block diagram of the implementation and analysis of the characteristics of the work; it reveals the advantages and disadvantages. The authors explain the features of the work of the functional circuits voltage regulators with discrete ballast, with phase control and management of the load current. It is shown, that to improve the performance of small hydroelectric power plants considerably we have to use contactless generators in their construction: asynchronous generators with capacitive excitation and synchronous generators with permanent magnets. The functional scheme of the voltage regulator, the construction of which has an additional field winding, simplifies the system voltage stabilization of the synchronous generator with permanent magnets, as well as a functional scheme of an asynchronous generator voltage regulator, made using step-up transformers, which significantly reduces the weight of the capacitors providing excitation of the generator and compensation of reactive power load. We have discussed the methods and devices for stabilization of voltage generators which will improve the effectiveness of pre-design work on the creation of new devices of stabilization of parameters of electric power generators for small hydroelectric power plants with improved operational and technical specifications
