The ECG shows evidence of severe left ventricular hypertrophy with prominent precordial voltage, left atrial abnormality, lateral ST-T abnormalities and a somewhat leftward QRS axis (-15 degrees).

心电图显示的证据，严重左室肥厚与突出的心前的电压，左心房异常，横向的ST - T异常和有点左QRS波轴（-15度）。

In this paper, some problems that have to be faced with in the application of SPLL to static synchronous compensator are analyzed, and two improvements of SPLL are proposed. The first one is removing the filtering function of lead-leg element into the prepositive delayed signal cancellation element to remedy the difficulty in deciding its parameters; the second one is directly taking the post-PI regulation output of q-axis voltage as error signal of phase to call off the forward integrating element.

分析了软锁相环应用于静止同步补偿器时面临的若干问题，并提出了2方面的改进方案：一是针对超前/滞后环节参数选取困难的问题，将其滤波功能转移到前置延时信号消除环节中；二是q轴电压经PI调节的输出直接作为相位的误差信号，减少了前向积分环节。
