Converter Station Fault Diagnosis and Maintenance

Project Background

The converter station is the foundation of the DC transmission project, and the converter valve is the core equipment of the converter station. If the cooling equipment fails and cannot be effectively cooled, it will cause power interruption, affect the economy and people's livelihood, and bring huge losses to society. Therefore, ensuring the "zero failure" operation of the equipment has become the core requirement of the converter station.

Project Solution

At present, the converter station needs to achieve the goal of "no emergency shutdown event". Therefore, taking the converter valve cooling system as the research object, through improving the equipment basic information database, setting the vibration and related process monitoring points, the monitoring and diagnosis methods for the equipment status of the cooling system are studied, and the monitoring and diagnosis technical rules for the converter valve cooling system of UHVDC transmission system are realized. The fault diagnosis analyzes the vibration data and frequency spectrum, predicts the possible location of the fault, and generates the maintenance work order; the real-time data of PLC is automatically associated in the maintenance work order to provide more accurate basis for maintenance. Through the optimization of monitoring means combination, as well as the improvement of platform auxiliary diagnosis and information management functions, the safe and stable operation cycle of cooling system is effectively improved, and the fault diagnosis and maintenance time is shortened. Carry out the whole life cycle management of the converter valve cooling system to provide good support for the later spare parts and maintenance service.

Solution Features
