Cutting-edge applications of second-hand generator recycling in Dongguan
1. Coordinated control of battery energy storage and generator in independent AC microgrid
In the independent AC microgrid system, the coordinated control between diesel generator and battery energy storage is the key to ensure the stable operation of the system. Based on the fast response characteristics of battery energy storage, a coordinated control method for diesel generators and energy storage batteries is proposed. Used Dongguan generator for recovery as a main power source, through the introduction of auxiliary power storage control system in a conventional droop control signal, when the diesel engine to prevent over-current caused by the collapse of long, improve the system stability. Aiming at the problem of short-term power outage when the main power in the microgrid is changed from the energy storage system to the diesel generator or from the generator to the energy storage system, a seamless switching control strategy for the dual main power of the generator and the energy storage battery is proposed.
2. Modeling and operation simulation study of marine generator set
The operation process of marine diesel generator sets is an important part of power station operation. The number of diesel generators operating in parallel determines the capacity of a ship's power station. The stability of parallel operation is closely related to the stability of the ship power station. The establishment of a mathematical model that can accurately reflect the operation of the used generator recovery unit in Dongguan is of great significance to the operation control, simulation and performance analysis of the power station. The study of the parallel operation process of generating units involves the establishment of a diesel generator model, a parallel operation control model, and an electric load model. Among them, although there are some different modeling methods for diesel generator models, most of them are limited to a single model simulation. With the diesel generator model as the core, a mathematical model for parallel operation of multiple generator sets is established. Taking the ship power station of the Yuyu ship as a reference object, a generator model, a power load model, and a parallel operation control system model were established. http://ftfan.cn/
