Abstract

When the input voltage and current of the distribution system in the RTU valve chamber of long-distance natural gas pipelines fluctuate, it may cause damage to the distribution system equipment, which in turn leads to reliability issues in equipment monitoring and remote data transmission during the production and operation of the valve chamber. This article designs an RTU valve room distribution protection system with PLC as the core. When the real-time sampled voltage and current of the system reach the protection action value of the distribution protection system, it can automatically cut off the mains power input. When the mains power returns to normal, it can automatically restore the mains power input. This protection system can improve the reliability of RTU valve chamber production and operation in long-distance natural gas pipelines, and has certain application value.
