3  Product plan

AcrelCloud-1000 The power operation and maintenance cloud platform is a modern Internet communication technology 、 Cloud computing 、 The comprehensive operation and maintenance monitoring platform of substation developed by popular technologies such as big data analysis . The cloud platform unifies the data collected by intelligent instruments and sensors through the high computing edge computing gateway 、 After standardized processing, it is wired / The wireless network transmission mode is uploaded to the cloud server for unified storage , And realize the online real-time monitoring of electric energy through the platform 、 Analysis of energy consumption 、 Lean management of equipment 、 Reasonable scheduling of tasks 、 Monthly report display and other functions , In order to help users analyze the substation operation environment , Reduce outage time , The purpose of ensuring stable power supply of power grid and safe operation of equipment .

AcrelCloud-1000 The substation operation and maintenance platform is designed with a hierarchical and distributed structure , The platform can be deployed on the hardware server purchased by users , It can also be deployed on the ECS rented by users （ Such as ali cloud 、 Tencent cloud 、 Huawei cloud, etc ）. The detailed topology is as follows ：

 

The power transformation and distribution room is equipped with a set of intelligent gateway , Collect the data of intelligent equipment in the substation , After protocol conversion 、 After compression and encryption, upload regularly or trigger upload platform , The platform can complete the data exchange of all intelligent devices in the power transformation and distribution room , It can monitor the transformer in the substation in real time 、 Operation status of important operating equipment such as circuit breaker ; Real time monitoring of the operation data, ambient temperature and other digital quantities of each circuit in the power transformation and distribution room ; The communication management unit is connected to the local area network in the plant , Send data to the data center .

The system can be divided into three layers ： That is, the field equipment layer 、 Network communication layer and platform management layer .

Field equipment level ： Including multi-function instruments installed in the substation 、 Temperature and humidity monitoring device 、 camera 、 Switching value acquisition device, etc . In addition to the camera , Other equipment passes through RS485 The bus is connected to the field intelligent gateway RS485 port .

Network communication layer ： Including on-site intelligent gateway, switch and other equipment . The intelligent gateway actively collects the data of field device layer devices , And protocol conversion , data storage , And upload the data to the specified server port through the switch , In case of network failure, the data can be stored locally , When the network recovers, continue to upload data from the interrupted location , Ensure that the server-side data is not lost .

Platform management ： Including application server and database server , If the number of substations is less than 30 Then the application server and database server can be configured in one . The server needs to have fixed IP Address , To receive the data actively transmitted by each intelligent gateway .
