Embodiment Construction

[0041] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0042] The independent microgrid of the present invention includes power generation units such as photovoltaic panel arrays, battery energy storage systems, and diesel generator sets. The power supply load of the independent microgrid is mainly the oil rig load, and there is also a barracks load. The oil rig load can be one of the DC oil rig or the AC oil rig according to the different needs of the site, and the two generally do not exist at the same time. The load of the barracks is mainly the load of the living area, including summer air conditioners, winter electric heaters, cooking equipment, hot water boilers, etc.

[0043] Such as figure 1 As shown, in the independent microgrid of the present invention, the diesel generator set is directly connected to the busbar, and the photovoltaic panel array and battery energy storage are both connected to the b...

Abstract

A power supply system for an oil drilling rig, using an independent micro-grid to supply power to the oil rig, and controlling the operation of the independent micro-grid through an expert strategy based on heuristic rules, taking into account the constraints of photovoltaic power generation, diesel engines and energy storage, Realize the stable, reliable and economical operation of the oil drilling rig power supply system. The independent microgrid includes a photovoltaic panel array, battery energy storage and diesel generator set; the diesel generator set is directly connected to the AC bus, and the photovoltaic panel array and battery energy storage are connected to the AC bus through DC / AC or connected to the AC bus through DC / DC. The DC bus is connected; the AC bus is connected to the DC bus through AC / DC. The oil drilling rig is a DC oil drilling rig or an AC oil drilling rig; the AC oil drilling rig is directly connected to the AC bus of the microgrid; the DC oil drilling rig is directly connected to the DC bus of the microgrid.

Description

technical field [0001] The invention relates to a power supply device for an oil drilling rig. Background technique [0002] With the continuous increase of people's demand for oil, oil drilling rigs have been paid more and more attention as an important equipment for oil extraction. At present, oil drilling rigs mainly rely on diesel generator sets for power supply. Since diesel engines generate noise during operation and pollute the environment, how to reduce the use of diesel engines in the power supply process is an important research topic. The rapid development of distributed power generation provides an opportunity to solve this problem. Utilizing distributed photovoltaics and energy storage to operate in conjunction with diesel engines to build an independently operating microgrid can improve the reliability and economy of power supply, and greatly reduce environmental pollution. [0003] Chinese patent 201510535648.3 discloses an intelligent oil drilling rig, whi...
