Why would it be necessary for a short duration of ultra high energy as strong as a nuclear power plant? I say it is tailored for Ultra High Power Laser Weapons. Or Giant Magnetic Rail Guns alike. Chinese already got petawatt laser. This is the power to supply energy to it.

由中核集团核工业西南物理研究院与哈电集团哈尔滨电机厂有限责任公司共同研制的该机组，总重约800吨、总高约15.5米，是为满足我国先进聚变研究装置中国环流器二号M（HL-2M）大功率、高储能供电需求研制的大型脉冲“能量驱动器”。
工作时，该机组发电机由电动机拖动15分钟后，转速可由0至每分钟498转，随后通过转子加励磁在15秒内将转速下降至每分钟335转，同时释放1350兆焦能量；发电机释放能量后，转速会再次提速到每分钟498转，并在保持5分钟后再次下降转速放电，完成一个工作循环。
“该机组的额定转速每分钟500转，总储能达到2600兆焦，额定电压3千伏、额定电流29千安，也是目前国内容量最大的立式六项脉冲发电机组。”李强说，比较原有“中国环流器二号（HL-2A）”使用的3台脉冲发电机组，“仅这一台新机组的释能能力和电功率输出均相当于此前3台的总和。”

脉冲发电机组分为立式、卧式两种，传统的卧式由于轴系受到转子及飞轮自重的限制，不便于设计成大容量脉冲发电机组；而立式机组的轴系是竖直的则没有这个问题。
“作为国内首台立轴式脉冲发电机，该机组无论从电机结构还是负载类型，都与常规的水轮发电机大不相同，此前甚至没有成熟的计算方法和设计经验，需要进行大幅度创新。”西物院聚变科学所副总工宣伟民说，巨大的脉冲发电机内，转子的转速不断变化，如何保持设备整体稳定性、震动幅度如何控制、冷却系统如何设计、六相电机程序如何编写都是前所未有的挑战。
最终，研发团队首创了多项特有技术，攻克了六相大电流发电机、大惯量高速转子、宽频变化控保系统等技术难题，在研制过程中形成了一批拥有自主知识产权的创新成果。
中国环流器二号M（HL-2M）是在我国首个具有偏滤器位形的大型托卡马克装置“中国环流器二号（HL-2A）”基础上新研制的又一大型托卡马克装置，其科研目标是探索可控核聚变研究，实现“人造太阳”的人类终极能源追求。该脉冲机组的成功研制，将驱动HL-2M装置的等离子体电流达到此前现有装置的2倍以上、等离子体温度超过1.5亿度，从而为在这个装置上开展近堆芯级参数下的等离子体物理实验和关键技术研究提供有力保障。

According to the "Science and Technology Daily" reported on January 17, on the same day, in the Southwest Institute of Physics of the Nuclear Industry of China Nuclear Group in Chengdu, China's first 300,000 kVA Angular pulse generator system passed the acceptance, and the overall parameters reached the international advanced level. .
"As a six-phase high-current pulse generator set, its discharge power in about 10 seconds during operation is equivalent to Qinshan Phase I nuclear power plant with an installed capacity of 300,000 kilowatts." Li Qiang, deputy director of the Southwest Institute of Physics Research and Fusion Science, Nuclear Industry Group Say.
China's first 300,000 kVA Angular pulse generator set This picture is from the Science and Technology Daily WeChat public number
The unit developed by the Southwest Institute of Physics of Nuclear Power Group and Harbin Electric Machinery Co., Ltd. of Harbin Electric Group Co., Ltd., with a total weight of about 800 tons and a total height of about 15.5 meters, is to meet China's advanced fusion research device China Circulator No. 2 M (HL-2M) large-scale pulse "energy driver" developed for high-power, high-energy storage power demand.
During operation, the unit generator is dragged by the motor for 15 minutes, the speed can be from 0 to 498 revolutions per minute, and then the rotor is energized to reduce the speed to 335 rpm in 15 seconds, while releasing 1350 megajoules of energy; After the machine releases the energy, the speed will increase again to 498 rpm, and after 5 minutes of hold, the speed will be discharged again, completing a working cycle.
"The rated speed of the unit is 500 rpm, the total energy storage capacity is 2600 megajoules, the rated voltage is 3 kV, and the rated current is 29 kA. It is also the largest vertical six-pulse generator set in China." Li Qiang said that comparison The original "China Circulator No. 2 (HL-2A)" used three pulse generator sets. "Only the discharge capacity and electric power output of this new unit are equivalent to the sum of the previous three units."
China's first 300,000 kVA Angular pulse generator system passed the acceptance
The pulse generator components are vertical and horizontal. The traditional horizontal type is limited by the weight of the rotor and the flywheel. It is not convenient to design into a large-capacity pulse generator set. The vertical unit's shaft system is vertical. There is no such problem.
"As the first vertical axis pulse generator in China, the unit is very different from the conventional hydro-generator in terms of motor structure and load type. Previously, there was no mature calculation method and design experience, and it required a lot of innovation. Xuan Weimin, deputy chief engineer of the Institute of Fusion Science, said that in the huge pulse generator, the rotor speed is constantly changing. How to maintain the overall stability of the equipment, how to control the vibration amplitude, how to design the cooling system, and how to program the six-phase motor. Writing is an unprecedented challenge.
In the end, the R&D team pioneered a number of unique technologies, which solved the technical problems of six-phase high-current generators, high-inertia high-speed rotors, and broadband-variable control systems. In the process of development, a number of innovations with independent intellectual property rights were formed.
China Circulator No. 2 M (HL-2M) is another large tokamak newly developed on the basis of China's first large tokamak device with a divertor configuration, "China Circulator No. 2 (HL-2A)". The scientific research goal of the device is to explore the research of controlled nuclear fusion and realize the ultimate energy pursuit of human beings. The successful development of the pulse unit will drive the plasma current of the HL-2M device to more than twice that of the prior device and the plasma temperature to exceed 150 million degrees, so as to carry out the plasma under the near-core level parameter on this device. Physical physics experiments and key technology research provide a strong guarantee.
