| 中文摘要:为提高对智能变电站过程层二次虚回路的自动控制抗干扰和校核能力，设计了基于线性扩张自适应控制的智能变电站过程层二次虚回路自动校核系统。建立了智能变电站过程层的二次虚回路等效电路模型，采用误差反馈校正方法调节模糊控制参数；在此基础上，进行智能变电站过程层二次虚回路的线性自抗扰控制和参数整定性处理，根据等效控制反馈增益的变化实现对过程层二次虚回路的自动校核。仿真实验结果表明，采用该方法进行智能变电站过程层二次虚回路自动校核的校核精度较高、可靠性较好，且校核过程较稳定，提高了智能变电站过程层二次虚回路的抗干扰能力，具有很高的应用价值。 |

| Abstract:In order to improve the automatic control anti-interference and check ability of the secondary virtual circuit in the process substation of intelligent substation，an automatic verification system for the secondary virtual circuit of the intelligent substation process based on linear expansion adaptive control is designed. The second virtual loop equivalent circuit model of the intelligent substation process layer is established，and the fuzzy feedback parameters are adjusted by the error feedback correction method. On this basis，the linear auto disturbance rejection control and parameter tuning processing of the secondary virtual loop of the intelligent substation process layer are carried out. According to the change of the equivalent control feedback gain，the automatic check of the secondary virtual loop of the process layer is realized. The simulation results show that the method of automatic verification of the secondary virtual circuit in the process substation of the intelligent substation has high calibration accuracy，good reliability，and stable calibration process，which improves the secondary virtual circuit of the intelligent substation process layer. Anti-interference ability，has high application value. |
