With the rapid advancement of global digital transformation, smart grid, as a key part of smart city, is developing at an unprecedented speed. The smart grid achieves intelligent management and optimized operation of the power system by integrating advanced communication, information, and control technologies. In this process, industrial wireless AP Access Point plays a crucial role as a bridge connecting the physical world and the digital world.

Industrial wireless AP, referred to as wireless access point, is a bridge between wireless network and wired network. It enables wireless terminal devices to access wired networks through wireless signals within the coverage area, thereby enabling data transmission and communication. Compared with ordinary wireless AP, industrial-grade wireless AP has higher reliability and adaptability, and is usually designed for industrial environments with higher network requirements, including large-scale wireless coverage, remote control transmission, wireless video transmission, and IoT intelligent control.

In the smart grid, the application of industrial wireless AP is mainly reflected in remote access and monitoring. By deploying industrial wireless AP, real-time monitoring and control of each node in the power grid can be achieved, improving the reliability and stability of the power grid. Here are some specific application scenarios and customized wireless AP solutions:

1. Distribution automation and remote meter reading:

Industrial wireless AP can be deployed in distribution substations to transmit meter data to data centers in real time through wireless networks, enabling remote meter reading. This can not only reduce the cost and error probability of manual meter reading, but also achieve fine management of energy usage and improve the efficiency of power marketing.

Customized wireless AP can support multiple communication protocols and data formats, ensuring compatibility with different brands and models of electricity meters, and achieving seamless access and data transmission.

2. Collection of fault indicator information:

Industrial wireless AP can connect to fault indicators to monitor faults in the power grid in real time. In the event of a malfunction, the fault indicator will immediately send an alarm message to the data center, assisting operation and maintenance personnel in quickly locating and repairing the fault.
Customized wireless APs can support low-latency, high-reliability communication, ensuring real-time transmission and processing of fault information.

3. Monitoring the status of charging stations:

With the popularity of electric vehicles, the number of charging piles is increasing. Industrial wireless AP can be deployed near the charging pile to monitor the working status and charging data of the charging pile in real time.
Customized wireless AP can support remote configuration and management, which is convenient for operation and maintenance personnel to monitor and maintain charging piles remotely.

4. Remote monitoring of unmanned distribution substation:

For widely distributed unmanned distribution substations, industrial wireless access points can connect video surveillance, temperature and humidity sensors, smoke sensors, and other devices to achieve comprehensive remote monitoring.
Customized wireless AP can support high-bandwidth, low-interference communication, ensuring real-time transmission and clarity of monitoring data.

5. Remote control of intelligent inspection robot:

Intelligent inspection robots are important equipment in the smart grid, which can autonomously or remotely inspect power grid lines and equipment. Industrial wireless AP can be deployed within the communication range of inspection robots to achieve remote control and data transmission.

Customized wireless AP can support stable communication in high-speed movement, ensuring real-time communication and control between the inspection robot and the data center.

In the solution of customized wireless AP, multiple factors need to be considered to ensure that it meets the special needs of the smart grid. These factors include:

● Coverage: Industrial wireless APs need to provide wide wireless coverage to ensure access and data transmission at various nodes in the power grid.
● Stability and reliability: The smart grid has extremely high requirements for the stability and reliability of communication, and customized wireless APs need to adopt advanced technology and redundancy design to ensure stable operation in harsh environments.
● Security: Customized wireless APs need to support multiple security protocols and encryption technologies to ensure the security of data transmission.
● Ease of use and maintainability: Customized wireless APs need to provide intuitive and easy-to-use management interfaces and remote configuration functions to facilitate management and maintenance by operation and maintenance personnel.

Industrial wireless AP plays an important role in remote access and monitoring of smart grid. Through customized wireless AP solutions, it can meet the special requirements of smart grid for communication stability, reliability, security and ease of use, and promote the efficient, green and sustainable development of smart grid.
