Embodiment Construction

[0022] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0023] refer to figure 1 , the energy management system of the offshore power grid of the present invention includes an information layer 10, a station control layer 20, and an interval layer 30, and the information layer 10, the station control layer 20, and the interval layer 30 are respectively arranged in the central control station 11 and a plurality of offshore platforms The platform workstation 12 of the power station, and multiple offshore platform power stations are set in one sea area, such as multiple offshore oil drilling platforms in the Weixinan oilfield group in the Zhanjiang sea area of ​​Guangdong. The distance between multiple offshore platform power stations is 10Km-60Km. The central control station 11 is preferably set on an island or on the shore. In this embodiment, the central control station...

Abstract

The invention discloses an energy management system of offshore grid, comprising an information layer, a station control layer and a spacing layer, wherein the information layer, the station control layer and the spacing layer are respectively arranged in a central control station and the platform workstations of a plurality of offshore platform power stations distributed in a sea area; the station control layer is connected and communicated with the information layer and the spacing layer through a communication network; the system carries out the monitoring and control of each generator set, the monitoring and control of each breaker, the distribution, adjustment and control of the reactive power and reactive power contribution, the control of the preferential trip, the management and control of the loop start of a motor, and the cooperative control of the black start of the grid and a platform shutdown system through the information layer, the station control layer and the spacing layer. The invention has the characteristics of high channel speed and degree of automation, highly integrated function, safe and reliable work, easy maintenance, and flexible configuration.

Description

【Technical field】 [0001] The invention relates to a power system of an offshore oil platform, in particular to an energy management system of an offshore power grid for real-time monitoring, control and management of a power grid composed of multiple offshore platform power stations distributed in a sea area. 【Background technique】 [0002] At present, all countries in the world are constantly strengthening the development and utilization of marine resources, especially the development and utilization of offshore oil and natural gas resources. Power supply is an important link in oil and gas development. Because most of the offshore oil and gas fields are far away from each other, in terms of mining methods, most of them at home and abroad currently use a central platform to build a power station to supply power for the central platform and each wellhead platform. This power supply method has the following problems: [0003] One is that the conventional offshore oil and ga...
