海浪槽锥发电机（SSG）是一种基于波浪越顶原理的波浪能转换器;它采用了几个相互叠加的水库，其中入射波的能量被存储为势能。然后，捕获的水通过涡轮机用于发电。该系统可在各种不同的波浪条件下工作，具有很高的整体效率。它可以适用于海岸线和防波堤应用，并具有特殊的优势，例如分担结构成本，电网连接的可用性和港口内的水再循环，因为涡轮机的出口位于系统的后部。最近，在Svaaheia站点（挪威）、Hanstholm港口（丹麦）和Garibaldi港口（美国俄勒冈州）进行SSG试点安装的计划正在进行中。在后两个项目中，将海浪槽锥发电机技术集成到外港防波堤和突堤改造工程中。在过去的几年中，广泛的研究已经进行了这种转换器的液压和结构响应，优化设计过程的目的。通过物理模型试验和数值模拟进行了研究，许多结果已发表在会议论文集和期刊上。本文的主要范围是回顾最重要的发现，为读者提供一个有机的概述知识的现状。
The Sea-wave Slot-cone Generator (SSG) is a Wave Energy Converter based on the wave overtopping principle; it employs several reservoirs placed on top of each other, in which the energy of incoming waves is stored as potential energy. Then, the captured water runs through turbines for electricity production. The system works under a wide spectrum of different wave conditions, giving a high overall efficiency. It can be suitable for shoreline and breakwater applications and presents particular advantages, such as sharing structure costs, availability of grid connection and recirculation of water inside the harbor, as the outlet of the turbines is on the rear part of the system. Recently, plans for the SSG pilot installations are in progress at the Svaaheia site (Norway), the port of Hanstholm (Denmark) and the port of Garibaldi (Oregon, USA). In the last-mentioned two projects, the Sea-wave Slot-cone Generator technology is integrated into the outer harbor breakwater and jetty reconstruction projects. In the last years extensive studies have been performed on the hydraulic and the structural response of this converter, with the aim of optimizing the design process. The investigations have been conducted by physical model tests and numerical simulations and many results have been published on both conference proceedings and journals. The main scope of this paper is reviewing the most significant findings, to provide the reader with an organic overview on the present status of knowledge.
