The design wave farm consists of 1000 units with 2MW plate capacity per unit (it is possible to use 4-500kW generators per unit or 2-1MW units) with average output of 50% capacity (1000MW wave farm).
The generators must supply a High Voltage Direct Current (HVDC) sea floor network where the 500,000 volt,1300 amp main transmission cable is connected to a static inverter station on land which connects to a regional power grid (phase load).This is a constant demand with strict phase requirements on land.
Our design allows the generators to be spun-up upon demand.Energy is stored in large volume hydraulic accumulators prior to spinning up generators with a hydraulic transmission.
We anticipate a tolerance in excess of +/- 1% per unit for voltage and current due to sea floor conditioning nodes that condition 100 units (100MW sea floor sub station)
A ripple coefficient under 0.1% is sufficient under full load
The generator units will be in a nitrogen

答案
此次设计的海浪场由1000个镀板组成,每个镀板容量为2兆瓦(也可采用4台500千瓦/台或2台1兆瓦/台的发电机),平均输出占总容量(即1000兆瓦的海浪场)的50%.发电机必须为海床网络提供高电压直流电,海床网络有50万伏特1300安的主传输电缆连接到静态陆地上的换流站又连接到区域电网上(相负荷).
该设计允许发电机根据需求自旋向上.通过水利传输发动发电机之前,能量储存在大容量的水利蓄水器里面.鉴于海床网络节点只容纳100个单位(100兆瓦海床变电站),我们预料电压和电流每单位会有+/-1%的浮差.0.1%的涟漪系数在全负荷状态下是充足的.单位发电机会放在一个装满氮气、靠压力补偿的容器里抛向海床.系统复位必须具备自动远距离能力.我们将会考虑生产商推荐的水平保护建议.
发电和传输首选直流电能量.
至今为止我们别无其他的技术要求.
此致!
