Abstract

The invention discloses a load distribution and control circuit of a diesel generating set speed controller. The load distribution and control circuit of the diesel generating set speed controller is composed of a load detection circuit module, a signal conditioning circuit module and a speed reduction control circuit module, wherein the load detection circuit module is composed of three groups of circuits. According to the load distribution and control circuit of the diesel generating set speed controller, through collection of voltage signals and current signals of each generator, output voltage, frequency and phase angles between generator sets are automatically adjusted, synchronization, automatic switching-on and connection to a grid of the different generator sets are realized, and impacts due to combination of the generator sets are effectively avoided. The load distribution and control circuit of the diesel generating set speed controller can realize load distribution and balance control when the multiple diesel generators are connected to the grid and in operation, wherein the load distribution and balance control includes the synchronization of power supply frequency of all the diesel generators in a grid-connected system and the load distribution and the balance among the different generator sets, and therefore the power supply quality and the power supply reliability of the grid-connected generator sets are improved.

Description

technical field [0001] The invention belongs to the technical field of load distribution and control of a speed controller of a diesel generator set, and in particular relates to a load distribution and control circuit of a speed controller of a diesel generator set. Background technique [0002] In the field of general power supply technology, electric energy occupies an important position, and the generation of electric energy mainly includes nuclear power, thermal power, hydropower and other methods. Nuclear power is clean and efficient, but humans cannot effectively control it; thermal power technology is mature and has been used by humans for the longest time; diesel power generation, as one of thermal power technologies, is mainly used in emergency power generation and power generation in special environments. Moreover, diesel power generation is widely used due to its advantages of energy saving, high efficiency and economy, such as ship power generation, nuclear powe...
