Embodiment Construction

[0053] Before carrying out the description of the specific embodiment, the industry terms involved in this field are described as follows:

[0054] (1) Wind farm: a power station consisting of a batch of wind turbines or wind turbine groups (including unit transformers), collection lines, main step-up transformers and other equipment.

[0055] (2) Numerical weather prediction: According to the actual situation of the atmosphere, under certain initial value and boundary value conditions, numerical calculations are performed by a large computer to solve the fluid dynamics and thermodynamic equations describing the weather evolution process, and predict the atmospheric movement for a certain period of time in the future Methods of states and weather phenomena.

[0056] (3) Wind power prediction: use the historical power of wind farms, historical wind speed, topography, numerical weather prediction, wind turbine operating status and other data to establish a prediction model of wi...

Abstract

The invention provides a wind power plant centralized control center centralized wind power prediction system. The system comprises: (1) a data source; (2) a data platform layer; (3) an application display layer. The centralized wind power prediction system adopts a micro-service software design mode. Each module in the system is a micro-service which can be independently split and deployed, a Docker container technology and a container cloud platform are used at the bottom layer, rapid iteration updating of the system is realized based on continuous integration and continuous deployment technologies on the container cloud platform, and the system is divided into an architecture of a production control large area and an architecture of an information management large area. The invention also discloses a design method of the centralized wind power prediction system for the centralized control center of the wind power plant. The design method comprises the following steps: 1) designing acentralized wind power prediction system network topology and a power monitoring system safety protection module; 2) designing a prediction result acquisition and display module of the concentrated wind power prediction system, and 3) designing an implementation strategy of artificially intervening the power prediction result.

Description

technical field [0001] The invention belongs to electric power systems, and in particular relates to a centralized wind power forecasting system and a design method for a centralized control center of a wind farm. Background technique [0002] In June 2011, the National Energy Administration issued the "Notice on the Interim Measures for the Management of Wind Farm Power Forecasting and Forecasting" (Guoneng Xinneng [2011] No. 177), requiring wind farms to be officially put into operation before July 2012. Wind power forecasting It has become a national mandatory requirement to configure a wind power forecasting system on the wind farm side. [0003] Wind power generation enterprises are faced with the serious problem of "wind curtailment" and the unfavorable external environment of "gradually lower" comprehensive on-grid electricity prices. In order to further reduce the operating cost of power generation, in recent years, various wind power companies have built wind farm ...
