Generator car distributed power supply control method based on flexible generator set

Abstract

The invention discloses a generator car distributed power supply control method based on a flexible generator set, and the method comprises the steps: integrating a corresponding energy storage system ESS for a synchronous generator SG of each generator car, thereby forming a flexible generator set FG; each flexible generator set FG is used for supplying power to the corresponding subsystem; an independent MPC control module is configured for each flexible generator set FG; the MPC control module collects operation state parameters of the corresponding subsystems in real time, performs model prediction control in combination with the reference signals, and outputs prediction control output quantity to the flexible generator set FG; and a controller of the flexible generator set FG takes the predictive control output quantity as a power supply control input quantity, and outputs power according to the power supply control input quantity. The technical problems that the data processing burden is too heavy and a large-capacity ESS needs to be configured in centralized control are solved.

Description

technical field [0001] The invention relates to the technical field of power supply control of a generator vehicle. Background technique [0002] The application fields of generator cars have been relatively extensive, such as emergency rescue and disaster relief, field construction, train power supply, etc., all need to rely on emergency generator cars to provide reliable power sources. In order to ensure the reliable power supply of emergency generator vehicles, many methods for the stability control of generator vehicles have been proposed. One of the methods is to apply the energy storage system (Energy Storage System, ESS) to the synchronous generator (Synchronous Generator, SG) inside the power generation vehicle to form a flexible generator set (Flexible Generator, FG). At present, in order to synchronize the power of each synchronous generator, a centralized control mode is adopted: one lumped ESS corresponds to multiple synchronous generators SG, and information ne...

AI Technical Summary

Problems solved by technology

At present, in order to synchronize the power of each synchronous generator, a centralized control mode is adopted: one lumped ESS corresponds to multiple synchronous generators SG, and information needs to be collected from different power networks and then transmitted to the central processing unit. The huge amount of data needs to be processed The controller brings communication delay and computing bottleneck

In addition, the aggregated ESS capacity is required to be large, and additional control is required to exit the ESS when the system reaches its nominal state
