摘要
Abstract
Aimed at the unbalanced voltage control method for power grid in the core circle of megacity is affected by nonlinear impulse load harmonics in practical applications,resulting in voltage overshoot.A method for controlling the unbalanced volt-age of power grid in the core circle of megacity based on nonlinear impulse load harmonic characteristic identification model is proposed.Based on the different structures and situations of the core circle of megacity,modeling is carried out using split bus capacitor structure and voltage balancer structure as examples to deeply analyze the voltage imbalance of nodes.The nonlinear impulse load harmonic characteristic identification model is used to classify the load harmonics and compensate for reactive pow-er to reduce the interference of load harmonics on the control process,and virtual inertia is introduced for calculation to achieve the control of unbalanced voltage of power grid in the core circle of megacity.The experimental results show that in the case of sudden load changes in the power grid,the bus voltage variation of the proposed method is 56％of that of the traditional con-trol method on average,and the voltage can be adjusted to the rated value in a shorter time,which has certain effectiveness.关键词
