Process

Virtual debugging uses digital twin technology to create a virtual environment that mirrors the physical telecom power system. Engineers build a digital replica of the cabinet, including all power modules, sensors, and communication links. This model receives real-time data from IoT sensors, which allows the digital twin to reflect the current state of the system.

Operators use this virtual environment to run diagnostic tests, simulate faults, and analyze system behavior without touching the physical equipment. They can identify issues such as voltage drops, communication failures, or overheating by observing the digital twin’s response to simulated scenarios. The process includes:

• Connecting live sensor data to the digital twin for accurate modeling.

• Running automated scripts to test different fault conditions.

• Using analytics dashboards to visualize system health and performance.

• Remotely adjusting parameters and observing the impact in real time.

This approach allows teams to troubleshoot problems, validate fixes, and optimize settings before applying changes to the actual telecom cabinet. As a result, they avoid unnecessary site visits and reduce the risk of accidental downtime.

Benefits

Virtual debugging delivers several key benefits for telecom power systems. It reduces operational costs, minimizes downtime, and improves fault detection accuracy. Operators can identify and resolve issues remotely, which leads to faster response times and fewer on-site interventions.

Virtual debugging empowers engineers to test solutions in a risk-free environment, ensuring only proven fixes reach the live system.

Simulation results show that IWSO outperforms traditional methods in tracking voltage fluctuations and handling varying load conditions, ensuring stable power delivery to telecom base stations.

In addition, fault simulation enables accurate prediction of network performance after faults occur. By modeling adaptive network behavior, operators can anticipate cascading effects and optimize fault handling strategies. The NAB-DQN method, for example, captures dynamic routing and queuing effects, allowing for precise performance prediction with less than 10% error and significant speed improvements over traditional simulators.

These capabilities collectively reduce downtime by:

• Enabling faster fault detection and response.
