变压器过载能力预警曲线
■ 主要功能
1）工况及温度场信息监测与预警：实时监测变压器运行负荷，变电站日照强度、环境温度、风速等；实时计算变压器内部顶层油温升、油平均温升、线油温差、绕组平均温升、绕组热点温升，并根据相应信息进行预警。
2）带负荷能力评估与安全风险管控：考虑变压器带载能力多元影响因素，融合变压器实时电气及环境量参数，以当前运行工况为初始条件，动态分析变压器在长期或设定安全运行时间时的安全带载能力、不同过负荷倍数下的安全运行时间，实现变压器带载能力及安全运行时间的可视化展示（绘制过负荷能力曲线）；
3）风扇自适应投切（可选）：根据变压器运行情况实现散热风扇的智能化投切控制，节能增效；
4）热寿命损失评估：根据实时负荷、运行温度等信息，实时评估变压器寿命损失，确保变压器在安全可靠运行前提下最大限度地延长其使用寿命；
5）变压器绝缘寿命监测与预警（可选）：基于油中溶解气体分析结论数据和特征值提取算法，判别变压器绝缘老化状态，及时预警变压器潜在绝缘风险。
■ 主要技术指标
1）系统可提升变压器年平均负载能力15%~30%，极端天气下负载能力提升5%~15%；
2）系统支持多种通讯协议：61850、101、104规约或自定义方式；
