Embodiment Construction

[0027] figure 1 Inside the dotted line box is a composition block diagram of the integrated generator controller of the high-voltage DC power generation system of the present invention. Depend on figure 1 It can be seen that the output signal of the exciter is controlled by the excitation relay, and the output signal of the excitation relay is rectified by the rectifier circuit. PMG It is sent to the main circuit of the voltage regulator connected to the excitation winding F of the main generator, and the digital signal processor DSP and peripheral circuits are connected to the main circuit of the voltage regulator through the interface circuit of the digital voltage regulator. The two current detection signals of the current detection sensor CT1 for detecting the output load current of the generator and the current detection sensor CT2 for detecting the differential current of the system are respectively input to the digital voltage regulation interface circuit. The digit...

Abstract

The disclosed controller includes following parts: after being rectified, the output of excitation relay connected to exciter is connected to main circuit of voltage regulator connected to the exciting winding of main generator; interface circuit of digital voltage regulator connected to the output end of the main generator; digital signal processor (DSP) and peripheral circuits. Through interface circuit, outputs of DSP and peripheral circuits are connected to main circuit of solid breaker connected to the out put end of the main generator. Being located at output end of main generator, outputs from two pieces of current test sensor are connected to digital voltage regulating interface circuit. Internal power supply circuit generates all operational power supplies needed by control circuits. Comparing with prior art, the invention solves issue of arc occurred in breaker, raises speed of switching response of breaker, reduces number of replaceable parts, and simplifies structure.

Description

1. Technical field [0001] The invention relates to a generator controller in an aircraft high-voltage direct current power generation system. 2. Background technology [0002] The high-voltage DC power supply system is the third aircraft main power supply system proposed on the basis of analyzing the potential shortcomings of low-voltage DC power supply and constant-frequency AC power supply and the development needs of aviation technology. It has the advantages of light grid weight, easy parallel connection and uninterrupted power supply, etc. advantage. The American fourth-generation fighter F-22 and helicopter RAH-66 have adopted 270V high-voltage DC power supply system. my country's research on aircraft high-voltage DC power supply system is still in its infancy. [0003] Since the rated voltage of the high-voltage DC power supply of the aircraft is 270V, ordinary contact switch appliances cannot be used due to the difficulty of breaking arcs at high altitudes. The ge...
