Overview

Wind farm EMSThe system is arranged in the wind farm monitoring room and consists of a wind turbine monitoring system, a wind farm power management system (energy management system), and a third-party interface system. It mainly includes functions such as wind turbine monitoring, data collection, data storage, data query, data presentation, web publishing, wind turbine management, wind farm scheduling, and security auditing.Wind farm EMSThe system is a component of the remote control system for wind farms, which consists of a network communication system and a wind farm monitoring and operation platform system.

General principle

(1) The system adopts advanced concepts, technologies, methods, and equipment, which are both reliable and mature, reflect the current level, and have development potential. The overall technical performance of the system should reach the current level in ChinaWind farm EMSAdvanced level of system construction, and maintain its progressiveness in a certain period of time.

(2) Security: Adopting a complete security architecture to avoid a security vacuum.

(3) The selection of system software and hardware should follow open system specifications and support multiple international standard protocols, including the use of open operating systems, databases, applications, development tools, interface protocols, etc.

(4) The system can operate normally 24 hours a day, 365 days a year, and all equipment has high reliability and excellent performance.

(5) The system administrator is able to maintain and manage the system, and during maintenance and repair, it does not affect the overall business operation of the system. At the same time, all documents of the recording system must be complete, accurate, and consistent, and the accuracy of physical connections must be accurately recorded in the corresponding documents. In addition to accurately recording themselves, various documents must also ensure logical consistency between each other. Facilitating user maintenance after handover.

System Network Structure

The EMS workstation (or server) is the core of the entire system. The EMS application layer interacts with PCS to achieve active power control, reactive power control, and functionality, which can meet the vast majority of functional requirements. The EMS server adopts a dual machine hot standby redundancy form, and the operating system adopts a domestically produced Unix or Linux secure operating system to ensure the security of network related system data. The equipment adopts rack mounted installation, and the supporting server cabinet is installed in the equipment container.

feature

（1）Wind farm EMSMainly used to collect real-time data from wind turbines, SVGs, and booster stations in wind farms, to achieve control over the overall active and reactive power output of the wind farm;

(2) Efficient tools for graphic configuration, template management, database management, algorithm configuration, and more. Easy to use, can greatly shorten the implementation cycle of the project;

(3) Support C/S structure, support real-time processing of multitasking and multi-user front-end and back-end;

(4) The system has cross platform running characteristics and can run on Windows, Linux, and domestic operating system platforms;

summary

ST865Wind farm EMSThe system has a unified monitoring system and data platform, and operators only need to complete the monitoring of the entire wind farm through one system; The system integrates data from various intelligent systems, and all field level statistical reports are automatically completed; Special technology can obtain a large amount of underlying data of wind turbines, deeply understand all states of wind turbines, and facilitate refined operation and maintenance; Can provide high-quality data of the entire wind farm to other systems. The system meets the requirement of monitoring no less than 300 wind turbines and is suitable for mixed installation of different units and components. It can achieve monitoring of no less than 300 units on one set of monitoring software, but allows server software to be distributed and configured with multiple sets of single servers. At the same time, the number of monitored units per unit can reach 100 (the number of monitored units per unit can be adjusted according to specific projects), and the data collection and display refresh frequency is not more than 1 second.
