| Popis: | Among the main methods of increasing the energy efficiency of power plants, the most significant in terms of achieving positive results and the possibility of their implementation are organizational methods. When choosing a methodology for determining the energy efficiency of a ship's power plant, it is necessary to take into account a combination of the following necessary conditions: ensuring control taking into account stochastic changes in the current fuel consumption values and minimizing the cost of purchasing and using control tools. Solving these two problems is an interconnected process. With respect to diesel generator sets, this is achieved by continuously measuring the current values at each of the three phases of the generator and the voltage in a short time interval in a discrete manner, followed by calculating the current power consumption values and approximating them to energy efficiency indicators. Tests of a prototype of an analytical energy efficiency control system implementing the proposed control algorithm on a transport diesel showed a sufficiently high correlation of the obtained results with data on monitoring fuel consumption by a volumetric method, satisfactory reliability of the system, as well as the possibility of saving fuel and energy resources. A further development of the proposed approach to energy efficiency control can be the use for these purposes of the current values of the torque and power of the diesel engine obtained by analyzing the dynamic characteristics of the torsional and oscillatory systems of marine power plants. |
