The article discusses negative consequences of a decrease in the quality of electrical energy when feeding ship receivers of electricity from coastal sources, a method is proposed to ensure an effective voltage regime in the electrical network when feeding ships of technical fleet and floating objects from the coast. Definition of the equilibrium voltage mode at the “shore-to-ship” power supply scheme is given, the equivalent circuit of supply line (feeder) for the river fleet is developed, significant regulatory effects of the “shore-to-ship” power transmission elements are determined. Experimental studies of static characteristics of floating crane of R-99 project have been carried out. According to the results of the experiment, regulating effects on the voltage of the complex load of 0.4 kV of floating crane were determined. A calculation program for personal electronic computers has been compiled, which provides an assessment of the impact of voltage deviations in electrical networks when regulating the load. The law of voltage regulation in the “shore-to-ship” power transmission is proposed. An experimental verification of effectiveness of proposed regulation law was carried out while ensuring the equilibrium mode.
