DSP BASED REAL TIME SIMULATION OF A SMALL HYDRO POWER PLANT

Abstract

Fast depleting natural reservoir and near saturation of larger hydro plants has prompted engineers to focus on other alternatives. Small hydro power is reemerging as one of the alternatives, which can be easily developed, are cost competitive and are minimally disruptive to the environment. This thesis covers the features and evaluation of a digital signal processor/computer-based simulator of a small hydro power plant to carry out real time simulation. Real-time simulation is synchronization with the actual behavior via a real-time clock and an interface system that allows the external systems to operate just as if they were connected to the real system. The basic mathematical models of each component of the hydraulic SHP are analyzed. With the DSP Processor, the transients of the different operating conditions of the generating unit could be calculated and simulated in real-time. The SHP Model represents the modeling of various components of high and medium head and small hydro plant. The main components of a hydroelectric system may be classified into two groups: the hydraulic system components that include the turbine, the associated conduits- like penstock, tunnel and its control system; and secondly the electric system components formed by the synchronous generator and its control system. Digital signal processing is concerned with the digital representation of signals and the use of digital systems to analyze, modify, store, or extract information from these signals. DSP starter kit TMS320F2812 member of the TMS320C28xTM DSP generation, is highly integrated, high-performance solutions for demanding control applications. Texas Instruments (TI) offers an extensive line of development tools for the C28x generation of DSPs, including tools to evaluate the performance of the processors, generate code, develop algorithm implementations, and fully integrate and debug software and hardware modules.
