摘要
本文推导了计及风光荷相关性的变压器特征温度的概率密度分布;针对变压器运行风险的评估,提出绝缘劣化概率(IDP)、绝缘失效概率(IFP)和寿命损失期望(ELOIL)指标,实现新能源基地送端电网的变压器运行风险评估。
The probability density distribution of characteristic temperature of transformers are derived considering the correlation wind power,photovoltalic and the load.For the assessment of the operational risk of transformer,construct IDP,IFP,ELOIL indexes,and the operational risk of transformers in sending grid with renewable energy base is assessed.
