Abstract

The invention relates to a photovoltaic and gas complementary power generation direct-current drive pumping unit system, which adopts a direct-current motor to replace a traditional alternating-current motor, and effectively solves the problem of overlarge current in the starting process. A gas generator can utilize liquefied petroleum gas, natural gas, coalbed methane and other gases. Liquefied petroleum gas and natural gas can be used for generating power when the gas yield is small at the initial stage of coal-bed gas well production; and after the yield of the coal-bed gas well is stable,the gas generator generates power by utilizing coal-bed gas. The problems of high cost, difficulty in ensuring power supply points and farmland occupation in existing coal-bed gas well power supply are solved, power is generated on site in a coal-bed gas well site, wiring and power supply point selection processes are omitted, additional farmland occupation is not needed, and the system has good expansibility and flexibility, and is safe, reliable and high in practicability.

Description

technical field [0001] The invention relates to the technical field of coalbed methane development, in particular to a photovoltaic and gas complementary power generation DC-driven pumping unit system. Background technique [0002] In the process of coalbed methane development, the construction of "power grid" is one of the necessary conditions. However, due to the limitation of geographical conditions, coalbed methane wells are mostly distributed between mountains and mountains, and there is no ready-made power transmission network available. The power point is connected to the mains. This power supply mode has the following three disadvantages: [0003] Upfront wiring costs are high. After calculation, the current integrated wiring cost is 400,000 yuan / km for high-voltage lines, 200,000 yuan / km for low-voltage lines, and an average of 300,000 yuan / km. In addition, the wiring project is also restricted by factors such as geography and weather, resulting in a certain time ...
