随着新能源发电换流器等电力电子设备在电力系统中的占比持续提高,电网强度逐渐变弱,在交流短路故障后极易产生暂态过电压,引发连锁故障。文中基于电压源换流器低电压穿越控制模型,首先,分析了暂态过电压产生机理及锁相环动态对暂态过电压的影响。其次,基于锁相环控制方程,求解故障三阶段锁相环相位的近似解析解,进而,由电压相量图推导暂态过电压解析式。然后,通过过电压解析式,得到控制参数对故障清除后暂态过电压水平影响的连续变化趋势。最后,利用MATLAB电磁暂态仿真,验证了所求并网点电压解析式及参数影响过电压机理相关结论的有效性。
With the continuous increase in the proportion of power electronic equipment such as new energy resource generation converters
the strength of the power grid is getting weaker. It is very easy to generate transient overvoltage after AC short-circuit fault
which triggers cascading failures. Based on the low voltage ride-through (LVRT) control model of voltage source converter (VSC)
firstly
this paper analyzes the generation mechanism of transient overvoltage and the influence of phase-locked loop (PLL) dynamics on transient overvoltage. Secondly
based on the PLL control equation
the approximate analytical solution of the phase for the three-stage PLL is solved
and the transient overvoltage analytical formula is derived from the voltage phasor diagram. Moreover
the transient overvoltage analytical equation is deduced from the voltage phase diagram. Then
the continuous variation trend of the influence of control parameters on the transient overvoltage level after fault clearing is obtained from the overvoltage analytical equation. Finally
MATLAB electromagnetic transient simulation is utilized to verify the validity of the derived analytical equation for the voltage at the grid-connected point and the conclusions related to the overvoltage mechanism influenced by parameters.
