The invention provides an offshore power grid electric energy scheduling and management and control system with an effective working condition screening function. The offshore power grid electric energy scheduling and management and control system comprises a basic monitoring function module used for completing acquisition and state estimation of basic data of each node of an offshore power grid and providing effective data for an advanced control function module, the advanced control function module comprising a topology analysis module, the topology analysis module which is used for obtaining the power grid topology condition of the whole offshore platform according to the basic data collected by the basic monitoring function module, state estimation and state online monitoring and screening out nodes with effective working conditions as the power grid control basis according to the topological conditions. The system is advantaged in that a complex network structure of the offshore power grid can be effectively simplified, all the effective working condition information of the offshore power grid is obtained, and a foundation is laid for making a stability control strategy of theoffshore power grid under different working conditions.
Description
technical field [0001] The invention relates to an offshore power grid electric energy dispatching and control system, in particular to an offshore island micro-grid dispatching and control system with effective working condition screening. Background technique [0002] As the scale of my country's offshore power grid continues to expand, the network structure is becoming more and more complex, and the working conditions of the platform change frequently, and the requirements for system security and stability are getting higher and higher. At present, the research on the stability and reliability of offshore platform power systems is still relatively scarce. Building a safe, stable and efficient offshore power grid automation system is an inevitable requirement for the development of offshore power grids. [0003] As the scale of my country's offshore power grid continues to expand, it is facing the following problems: 1) The network structure is becoming more and more compl...
