Embodiment Construction

[0021] In order to make the technical problems, technical solutions and benefits to be solved, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention.

[0022] On the one hand this application proposes a method for controlling offshore grid stability, grid control server used in the sea, such as figure 1 with figure 2 As shown, including the following steps:

[0023] S1, power may be provided offshore unloading and loading unloading priority of each load can be unloaded;

[0024] Among them, pointing to the sea offshore grid power supply system of units, such as islands, offshore oil field power system. Typically, offshore grid comprises a plurality of load, some load may be unloaded, unload some not, offshore platform implementation-defined grid load can...

Abstract

The invention discloses a control method for stabilizing an offshore power grid, a control server and a storage medium. The method comprises the following steps: setting unloadable loads of the offshore power grid and unloading priority levels of the unloadable loads; monitoring and collecting the working state of the generator in real time; if it is monitored that a single generator or multiple generators trip, calculating the hot standby RPI and the total power ALT of the unloadable load, if the hot standby RPI is larger than 0, determining that the load does not need to be unloaded, and if the hot standby RPI is smaller than 0 and the sum of RPI and ALT is smaller than 0, starting a cold standby generator; and if the hot standby RPI is smaller than 0, and the sum of RPI and ALT is larger than or equal to 0, determining the load unloading sequence according to the unloading priority level of the loads, and unloading the loads till the hot standby RPI is larger than 0.

Description

Technical field [0001] Technical Field The present invention relates to a control offshore grid, particularly to a method for controlling marine power grid stability control server and a storage medium. Background technique [0002] With the gradual expansion of offshore oil field power system operation mode and more complex, more difficult to ensure the safe and stable operation of the system is also growing, so that the security and stability of the power grid issues become more prominent. Compared with onshore grids, offshore oil field power system capacity is small, the generator tripping, local small interfering or abnormal operation of the entire system can cause a chain reaction of negative, impact on system stability, voltage and frequency will, and even lead to a large area system breakdown. To ensure the operational stability of the offshore platform, the need to study a method of controlling offshore grid stability. Inventive content [0003] In view of this, the pres...
