“…In practical applications of MHPPs, either some parts are not used or the functions of these parts are fulfilled by other components under certain assumptions [4,5,9,[16][17][18][19]. These assumptions help prevent most of the problems beforehand.…”

Abstract:In this study, a new approach that is closer to the real turbine without abandoning the advantages of nonlinear modeling simplicity compromising the simplicity of the nonlinear model is proposed. The purpose of the study is to contribute to making theoretical studies of microhydroelectric power plants (MHPPs) more realistic. Studies on their control, especially frequency control, have increased with the expansion of grid-connected power plants. However, some problems have occurred when converting simulation studies of the frequency control to practical studies. The reasons for these problems are that the systems cannot be modeled completely. In this study, first, the nonlinear model equations of a Pelton turbine are primarily constituted. The efficiency curve of the turbine is then obtained experimentally and added to the nonlinear model. The simulation results are compared with the data obtained from the prototype MHPP with a Pelton turbine developed in the laboratory. Finally, it is seen that the proposed method is successful. Thus, with the help of the proposed method, theoretical studies that researchers do can be easily converted into practical applications.

“…Many studies have been conducted on AVRs, which control the output voltage of synchronous generators. These are control methods performed together with various algorithms such as traditional PID implementations [9][10][11][12], cuckoo search algorithm [13], particle swarm optimization [14], coyote optimization algorithm [15], whale optimization algorithm [16,17], nonlinear robust coordinated [18], PSS and H∞ optimization [19] and kidney-inspired algorithm [20]. In addition to traditional PI and PID applications for the control of load frequencies of synchronous generators and power systems, control methods used with different algorithms, artificial intelligence and optimization techniques are also seen.…”

In this paper the design, manufacturing and automation of a micro hydroelectric power plant (MHPP) prototype has been carried out. The experimental setup consists of three 1 kW synchronous generators (SGs) working in synchronization with each other and with the grid, three Pelton turbines with a single nozzle manufactured using a 3D printer, a water tank with a capacity of approximately one ton, a 5.5 kW centrifugal pump providing appropriate flow and head conditions and an 11 kW driver controlling the speed of this pump. The mechanical and electrical structure of the system and its working scenario are designed to be the closest to a real MHPP. S7-1200 PLC (Programmable Logic Controller) is used in order to control the voltage and frequency values of synchronous generators according to the load as well as for other control processes. In this study, PID control method is preferred for frequency and voltage control. It is possible to control and monitor the whole system through SCADA (Supervisory Control and Data Acquisition) screens. The results have been evaluated by obtaining frequency-time, voltage-time, active power-valve opening, excitation current-reactive power graphs of synchronous generators under different load conditions and in single, local and synchronous operating modes.
