Joint optimization

跟prony算法一样，ESPRIT（Estimation of Signal Parameters Via Rotational Invariance Techniques）也是一种参数法，它是一种基于旋转不变技术参数估计的信号处理方法，此方法可以高精度地辨识电力系统中任意组合的衰减/非衰减正弦信号的频率，相位及其幅值等信息。它不需要对信号进行同步采样。此方法把信号空间分解为信号子空间和噪声子空间，能够在较短的信号长度内准确的检测出信号中各个谐波和间谐波成分。(ESPRIT)

仿真模型中，通过1000MW(5OOkv, 2kA)的直流输电线路从一个500KV、5000mva、50hz的电力系统EM向另一个345kv10000mva50hz的电力系统Ell输送电力。整流桥和逆变桥均由两个通用6脉冲桥搭建而成。交流滤波器直接接在交流母线上，它包括11次、13次和更高次谐波等单调支路。总共提供600mvar的容量。(In the simulation model, the 1000MW (5OOkv, 2kA) DC transmission line transfers power from one 500KV, 5000MVA, 50Hz power system EM to another 345kv10000mva50hz power system Ell. The rectifier bridge and the invert bridge are all constructed by two general 6 pulse bridges. The AC filter is connected directly to the AC bus, which includes 11 or 13 and higher harmonics. A total capacity of 600mvar is provided.)
