Closely related to the safety and stability of power grids,stability analysis has long been a core topic in the elec-tric industry.Conventional approaches employ computational simulation to make the quantitative judgement of the grid sta-bility under distinctive conditions.The lack of in-depth data analysis tools has led to the difficulty in analytical tasks such as situation-aware analysis,instability reasoning and pattern recognition.To facilitate visual exploration and reasoning on the simulation data,we introduce WaveLines,a visual analy-sis approach which supports the supervisory control of multi-variate simulation time series of power grids.We design and implement an interactive system that supports a set of analyt-ical tasks proposed by domain experts and experienced opera-tors.Experiments have been conducted with domain experts to illustrate the usability and effectiveness of WaveLines.

针对大规模逆变器接入弱电网易引起宽频带振荡,影响自身及系统的稳定运行的问题,结合PWM控制的三相桥式逆变电路,研究了脉冲宽度调制技术及死区效应下的逆变器并网口输出电压的谐波特性,以及LCL滤波器的固有谐振点以及控制延时对谐波的影响.通过在仿真平台搭建模型,实现了逆变器谐波特性的复现.结果表明,PWM调制技术会产生载波频率及其整数倍附近的高次谐波;死区效应增加了逆变器输出波形的低次谐波,且随着死区时间的增加,5次和7次谐波含量增加;控制延时将造成滤波器谐振频率的偏移.
