Abstract

Abstract

To solve the problem of difficult power supply for the equipment in the pressure regulating station along the natural gas pipeline, a small power generation control system suitable for 10~40 kPa natural gas low-pressure differential power generation was designed. The domestic chip was selected as the main control chip of control system, and the permanent magnet synchronous generator PMSG was selected as the energy recovery device of front end. In the designed hardware circuit of the control system, the maximum power point was used as the control output, and it met the explosion-proof requirements by using the intrinsically safe circuit. Lithium titanate battery was used as energy storage and instrument equipment. In the program design, the control of pipeline solenoid valve was realized to solve the problem of input overload under the condition of fully charged battery and excessive high voltage difference, and a variety of protection strategies were used to prevent the high voltage after rectification from damaging the components. The performance of the control system was tested through the construction of the test-bed, and the function basically can meet the expected requirements.
