为了感谢惠俊英老师的谆谆教诲，特为好奇诸君再奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，又轻松跑完9份作业（9路招式），即悟简正波海洋声场传播模型之能耐！ KRAKEN与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对KRAKEN的原创。也感谢由Free Software凝聚起来的自由科学家社区。 本秘籍适合大三以上和非水声物理专业同志们的快速参学。 吴开明 2018.12(The KRAKEN model was initially developed as a research code to evaluate new algorithms. As such it required numerous modifications to be usable as a production code. This work was begun at the Naval Ocean Systems Center and continued at the Naval Research Laboratory in support of the research on matched-field processing.)

本模型采用矢量控制与SVPWM相结合的方法，应用在低压微电网中。直流源电压为600V，逆变器输出电压为380V，可实现稳定功率输出。模型对网侧控制策略中每一模块尽量做出了说明，方便初学者更快理解三相逆变器控制策略的实现方法，运行效果非常好。(This model adopts the method of combining vector control with SVPWM, which is applied in low voltage microgrid. The DC source voltage is 600V, and the inverter output voltage is 380V, which can achieve stable power output. Each module is explained as far as possible in the network side control strategy. It is convenient for beginners to understand the realization method of the three-phase inverter control strategy faster, and the operation effect is very good.)
