【摘要】:在大型电弧炉的补偿应用中,为了应对电网电压不对称的应用条件,提出一种35 k V直挂式角接链式STATCOM网侧电流闭环综合补偿控制策略。该策略将经典电纳平衡补偿和网侧电流闭环控制相结合,使得链式STATCOM装置可以在电网电压不对称条件下对电弧炉负载进行无功、谐波和负序的综合补偿。经35 k V/±40 MVA STATCOM装置实际运行,结果表明:STATCOM装置能够在保持快速的动态响应的同时,实现良好的稳态补偿效果,并能抵御电网电压不平衡造成的影响。
[Abstract]:In the application of large electric arc furnace compensation, in order to deal with the application condition of voltage asymmetry in power network, a 35 kV direct mounted angle link STATCOM current closed loop compensation control strategy is proposed. This strategy combines the classical compensation with the closed loop control of the grid side current, which makes the chain STATCOM device can compensate the electric arc furnace load with reactive power, harmonic and negative sequence under the condition of the asymmetry of the grid voltage. The actual operation of the 35kV / 卤40 MVA STATCOM device shows that the STATCOM device can maintain fast dynamic response and achieve a good steady-state compensation effect, and can resist the influence caused by the unbalanced voltage of the power network.
