摘要

风储一体化系统即配备储能的风力发电，具有黑启动能力，对其加以控制可将该系统作为黑启动电源。基于此，在单台风机的基础上，制定了风储一体化系统的黑启动方案。首先，通过构网型控制的储能装置进行启动，为避免变压器投入过程中的励磁涌流或谐振产生的自励磁，在原有的电压环控制基础上，加入了惯性环节来实现软启动策略；然后，储能系统建立交流频率和电压后，实现风电机组及负荷的恢复；在风储一体化系统稳定启动后，经过主变压器和输电线路将电能输送到35 kV母线，完成黑启动过程。最后，在PSCAD/EMTDC软件平台建立风储一体化仿真模型，验证了采用软启动策略的黑启动方案，验证过程电压保持稳定，功率平衡，系统完成启动，同时有效地抑制了励磁涌流。

Abstract

Integrated wind storage system

namely the wind power generation equipped with energy storage

has a black-start capability

which can be controlled to use the system as a black-start power source. On this basis

a black start program for the integrated wind storage system is developed based on a single wind turbine. Firstly

the energy storage device is started through grid-forming control

and to avoid the self-excitation generated by excitation inrush or resonance in the process of transformer input

the inertia link is added based on the original voltage-loop control to realize soft-start strategy. Then

the energy storage system establishes the AC frequency and voltage to realize restoration of the wind turbine generators and the loads. After the wind-storage integrated system is stably started

the electrical energy is transmitted to the 35 kV busbar through the main transformer and transmission line

to complete the black start process. Finally

a simulation model of the integrated wind-storage system is built on the PSCAD/EMTDC platform to validate the black-start scheme using the soft-start strategy

which keeps the voltage stable and the power balanced

and completes the start-up of the system

and at the same time suppresses the excitation inrush current effectively.
