摘要:
海洋石油平台微电网是海上石油平台非常重要的组成部分，其稳定性对海洋石油平台的安全起着至关重要的作用。因此，建立海洋石油平台微电网模型，进而研究它的稳定性，有助于监测及评估海洋石油平台微电网的安全状态，为平台电气工程师及管理、运行人员提供安全运行预警及策略建议，有助于提高海洋平台的安全运行水平，具有非常重要的理论价值和现实意义。本文首先介绍了海洋石油平台微电网的相关特点，接着对其燃气轮机的主要构成部分进行分析，并用PSCAD软件建立相关模型，最后根据微电网的电路结构示意图建立相关模型，对微电网以电动机为主要负荷时，在不同运行状态和电动机负荷所占比重不同的情况下，进行一系列仿真，得出相关结论。
Offshore oil platform micro grid is a very important part of offshore oil platform, and its stability plays an important role in the safety of offshore oil platform. Therefore, establishing mathematical model of offshore oil platform of the micro grid and studying its stability helps monitor and access the safety state of offshore oil platform of the micro grid, and this provides early warning strategy and suggestions for the electrical engineers and management personnel operating platform and does good for improving the safe operation level of the offshore platform. These actions are of much theoretical value and realistic meaning. This paper first introduces the characteristics of offshore oil platform of the micro grid, then analyzes the main components of gas turbine, sets up the model by PSCAD, and establishes the model according to the circuit structure of the micro grid diagram. It carries out a series of simulation in different operating conditions and different motor load proportion by assuming the motor as the main load first and gets relevant conclusions.
