Technical Field

The invention relates to the technical field of power generation equipment, in particular to a double-rotor single-stator phase modulator.

Background

With the rise of new energy power generation technology and the attention paid to green energy, more and more new energy power generation modes such as photovoltaic power generation, hydroelectric power generation, wind power generation, nuclear power and the like in the world are merged into a power generation network, but the brought result is that the proportion of traditional thermal power generation is less and less, so that rotating equipment accessed in the system is reduced, the inertia of the system is indirectly reduced, and when the system is disturbed, such as active shortage, a large number of new energy power stations are disconnected from the power network due to the fact that no buffering is brought by the rotating equipment, so that the power network is subjected to unpredictable impact, and even the system is completely broken down. Therefore, the system inertia problem is one of the problems of thousands of problems brought by the existing extra-high voltage direct current transmission and the large amount of new energy grid connection. However, the new synchronous phase modulator as a reactive power compensation device of a high voltage direct current transmission system has a rotational inertia to buffer the system fault, so that the new synchronous phase modulator is required to provide all the lacking active power to the system. The novel synchronous phase modulator is improved, so that the novel synchronous phase modulator can play a role of a large-capacity reactive power source, and can also provide partial active power when the system is lack of active power to relieve the impact of a power grid so as to protect the operation stability of a power system.
