Power supplying system with multiple large-power high-voltage diesel generating sets in parallel operation

Abstract

The invention discloses a power supplying system with multiple large-power high-voltage diesel generating sets in parallel operation. The system includes the high-voltage diesel generating sets, a high-voltage parallel operation system, a comprehensive protection device, a non-electricity protection device, a PT cabinet and a grounding resistor cabinet. The device has an independent-power-station design and under a condition without power grid voltage, the operation states of the generating sets can be adjusted according to external factors such as the operation condition of a main generator and electrical power parameters and the like and when in an emergency condition or when operation of the generating sets is needed, the parallel operation system is put into operation automatically so that grid connection use of any one or more generating sets in the system can be realized. An integrated console realizes concentrated monitoring and operation logic processing of the parallel system and automatic connection, automatic load sharing and automatic disconnection can be completed together and slope loading and slope unloading functions and control of automatic cooling stop are supported and system time and timer time can be set respectively according to the use condition and project demands and the whole parallel system is capable of automatically adjusting the number of sets which are put into operation according to the capacity of the load so as to meet stable power supply of the load.

Description

technical field [0001] The invention relates to the technical field of high-voltage diesel generator sets, in particular to a power supply system in which multiple high-power high-voltage diesel generator sets operate in parallel. Background technique [0002] With the rapid development of my country's national economy, the demand for electricity and the security of electricity in all walks of life are also increasing. With the increase of single-unit power generation capacity, my country has entered the era of large units, high voltage and high automation. . Emergency power consumption and urban peak regulation in mines, ports, docks, islands, large data centers, large high-rise urban complexes, industrial districts, etc. require multiple high-power diesel generators to be connected to the grid to meet the load requirements, and for individual computer rooms and The distance between the loads in actual use is far away, and the parallel operation of multiple low-voltage dies...
