DSBC176 3BSE019216R1 ABB 接口模块
在初始订购阶段就可以定制,并且可以在数字化变电站的寿命周期内进行灵活的修改。SSC600已准备好与电网共同升级,以适应不断变化的保护要求。持续访问软件动态将保证变电站系统的先进性。升级整个变电站系统比以往任何时候都容易,只需更新一个设备,而不需替换所有间隔层的保护和控制设备。
通过集中式人机界面(HMI),用一个设备监视和控制各种变电站设备,这一能力将提高对系统的状态感知,从而更易获取有价值的配电过程信息
DSBC176 3BSE019216R1 ABB 接口模块整个系统工作流程可以简单描述如下:系统上电后,首先DSP由flash实现自举,并运行引导程序,之后转入EDMA等待状态,FPGA初始化后等待外部图像采集命令,收到图像采集命令后开始进行图像采集,并对采集到的图像进行预处理,预处理后的图像经过FIFO缓冲,在存储一定量的数据之后,FPGA通过半满信号向DSP发送EDMA请求,等待DSP响应,DSP一旦收到来自FPGA的EDMA请求,立即建立EDMA通道,从FIFO中读取数据到L2存储器,存满一帧图像后DSP开始图像压缩,等待一幅图像压缩完成之后,DSP会向FPGA发送中断信号,FPGA在收到中断信号后开始从 FIFO中读取压缩后的图像数据。一帧数据读完后,判断编码信号是否有效,如果有效则按同样的规则对下一帧图像进行压缩,如果无效则通知DSP结束。

It can be customized at the initial ordering stage and can be flexibly modified during the life cycle of digital substation. SSC600 is ready to upgrade with the power grid to meet the changing protection requirements. Continuous access to software dynamics will ensure the advanced nature of substation system. It is easier to upgrade the whole substation system than ever before, only one device needs to be updated, and it is not necessary to replace all the protection and control devices in the bay floor.
Through the centralized man-machine interface (HMI), one device can monitor and control all kinds of substation equipment, which will improve the state perception of the system and make it easier to obtain valuable information about the distribution process.
The whole system workflow of DSBC176 3BSE019216R1 ABB interface module can be simply described as follows: After the system is powered on, first, the DSP is bootstrapped by flash, and the boot program is run, and then it turns to the EDMA waiting state; after the FPGA is initialized, it waits for the external image acquisition command, and after receiving the image acquisition command, it starts to acquire images and preprocess the acquired images. The preprocessed image is buffered by FIFO. After storing a certain amount of data, FPGA sends an EDMA request to DSP through a half-full signal, waiting for the DSP to respond. Once DSP receives the EDMA request from FPGA, it immediately establishes an EDMA channel, reads data from FIFO into L2 memory, and starts image compression after a frame of image is filled. After an image compression is completed, DSP sends an interrupt signal to FPGA, and FPGA starts reading the compressed image data from FIFO after receiving the interrupt signal. After reading a frame of data, it is judged whether the coded signal is valid. If it is valid, the next frame of image is compressed according to the same rules. If it is invalid, it is notified to DSP to end.
