为了更好地进行谐波和无功功率的补偿与控制，叶FBD(Fryze一Buchholz一DPenbrock)法的定 义进行了完善，并给出了补偿电流检测的直接法和间接法，在三相电力系统中对FBD间接法进行 了推广研究，利用参考电压进行投影变换，不仅可以检测出功率电流和零功率电流，还可以检测出 基波有功电流、基波无功电流、谐波电流以及任意次谐波电流等，大大拓展了FBD法的应用范围和领域。MATI一AB仿真和实验结果表明了所定义和推广的电流检测方法的正确性和有效性。 (In order to improve the performance of active power filter(APF) harmonic current detection method, a harmonic current detection based on FBD(Fryze-Buchholz-Dpenbrock) algorithm was proposed. Reference voltage was generated by phase locked loop(PLL), and load current was projected to reference voltage, and then the active power fundamental current, reactive power fundamental current, harmonic current, fundamental negative sequence current, any harmonic current and so on can be detected accurately by using low-pass filter(LPF), and in the case of distorted voltage, the method was also applicable. The simulation results verify the fast dynamic speed, high detection accuracy, simple implement and good project value of the proposed algorithm. MATLAB simulation results confirm the feasibility and validity of the method.)

哈尔滨工程大学word格式论文，基于差分演进算法的TDOA定位技术。提出了三种新的定位算法：基于TDOA的Chan-GA算法、Chan-DE算法和Chan-IDE算法。并在相同的仿真环境下进行比较，仿真结果表明，在保证种群数量的情况下，所提的算法性能稳定，能找到逼近全局最优点的解，相对于Chan算法精度更高,相对于以前的算法在保证收敛性能的前提下有更快的收敛速度。(Harbin Engineering University, word format papers, based on differential evolution algorithm TDOA positioning technology. Proposed three new localization algorithm: Based on TDOA Chan-GA algorithm, Chan-DE algorithm and Chan-IDE algorithms. And in the same simulation environment to compare simulation results show that, in the case of populations to ensure that the proposed algorithm performance and stability, can be found close to the global optimal solution, Chan algorithm with respect to higher accuracy compared to the previous algorithm convergence performance guarantee under the premise of a faster convergence.)
