Description

The invention relates to the field of automatic control and management and can be used in ship power supply systems of consumers. There are known devices for controlling the power of power plants, containing switches and load cells for generators flj. The disadvantage of such devices is the impossibility of measuring the total load. The closest to the technical essence of the invention is a device for monitoring the power of electrical power containing generator load meters, switches and signal contacts of switches 23. A disadvantage of the known device is low speed in control mode. The purpose of the invention is to increase the speed of the device. This goal is achieved by the fact that the device contains generators load level indicators, the first, second, third, fourth, fifth and third roles, the element is NOT and the element is AND, the first input of which is through the series-connected first expansion contacts of the first, second, third, fourth relay , the first closing contacts of the first and mecTOIX relays, and through the first closing contact of the first relay connected in series, the second opening contacts of the second, third, fourth, fifth relay and the first closing contact of the sixth p Barely, as well as through the serially connected first closing 1st contact of the first raula, the second closing contact of the second role, the third disconnecting contacts of the third, fourth, fifth and sixth rails are connected to the first inputs of generators load level alarms, the second inputs of which are connected to the outputs of the corresponding load meters generators, and the outputs - respectively through the third closure of the first, second, third, and fourth (
