Embodiment Construction

[0041] The present invention provides a new space nuclear power supply system and its time-sharing multi-form power management strategy. In order to make the present invention more obvious and understandable, the present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Such as figure 1 As shown, the new space nuclear power system of the present invention includes a nuclear reactor N, a thermoelectric conversion system M, a storage battery B, a parasitic load R and a load R1.

[0043] The nuclear reactor N is a device that realizes a controllable fission chain reaction by assembling nuclear fuel, which can output heat energy.

[0044] The thermoelectric conversion system M is connected to the nuclear reactor N, and the thermoelectric conversion system M can convert heat energy generated by the nuclear reactor N into mechanical energy. The thermoelectric conversion system M can also convert the...

Abstract

The invention discloses a novel spatial nuclear-electric power supply system and its time sharing multiform power management strategy. The novel spatial nuclear-electric power supply system comprisesa nuclear reactor, a thermoelectric conversion system, a storage battery unit, and a parasitism load; the nuclear reactor generates heat energy, and the thermoelectric conversion system converts heatenergy to power energy; the power energy is regulated and controlled through charging or discharging the storage battery unit and performing dissipation control on the parasitism load. From views of response time of load dynamic change and the adjusting power, the power management strategy comprises four power adjusting stages which are charging and discharging of the storage battery, dissipationof the parasitism load, work medium flow regulation, and control bar control. The novel spatial nuclear-electric power supply system has the advantages of realizing regulation of 'small' and 'big' powers output by the spatial nuclear-electric power supply system and control of 'instant' and 'long-time' load responses, and satisfying requirements of the load on the response time of the spatial nuclear-electric power supply system.

Description

technical field [0001] The invention relates to the technical field of power management of spacecraft power supply systems, in particular to a new space nuclear power supply system and its time-sharing multi-form power management strategy. Background technique [0002] On the surface of the moon (Mars), due to the long moon / fire night, surface dust, and low illumination constant, the power generated by the solar array cannot meet the mission requirements. [0003] Due to the characteristics of not relying on solar radiation, long life, and reliability, the nuclear power system can meet the requirements of high-power power supply, long shadow cycle and working environment away from the sun; in addition, under the high power of tens of kilowatts or more, its Specific power and other indicators are significantly better than solar power systems. [0004] The replacement of solar power systems by nuclear power systems has become the preferred energy supply solution for missions ...
