Research on High-Voltage Transmission System Operation on the Same Tower

Abstract

The high-voltage DC adopts the simulation idea of a two-circuit system on the same convertor. The current DC system availability indicators were insufficient and proposed two reliability indicators, operating utilization and operating availability. At the same time, the active planned outage mode and the activities planned energy unavailability rate index was proposed, and the reliability evaluation program algorithm analysis based on programming developed to verify the feasibility of the power outage maintenance optimization mode, and at the same time provide certain guidance and reference significance for the subsequent design work of the same type of research. A calculation algorithm for evaluating the impact of the outage DC on the reliability of the system is proposed to calculate the value of the transmission system.
