The cable life loss calculation method of new energy generation

The rapid development of new energy power generation has also driven the construction of outgoing transmission channels. Due to the characteristics of new energy with strong volatility and low annual utilization hours, it is difficult to maintain full operation for a long time, making it hard to accurately estimate the life of supporting outgoing transmission lines. In this paper, the output model of new power generating model is constructed to simulate the new energy output in the future for a long time for accurately analyzing the characteristics of the new energy volatility output. Then using the new energy output data, combined with the thermal circuit model and the IEC related standards, the thermal aging law of new energy generation outgoing transmission line is simulated and analysed, and the life loss calculation method of outgoing new energy generation transmission line is proposed. The simulation results show that the line life loss presents a process of fluctuation accumulation in the new energy generation environment, and there is still a huge transmission potential when the design life is reached.
