Background and challenges

"Energy development strategy action plan (2014 - 2020)", the action report pointed out: to optimize the energy structure, the development of clean low carbon energy as the main direction of the energy structure adjustment. The huge wind as a clean and renewable energy reserves, thus favored. However, because of the wind power of many requirements for location and land taken into consideration, wind farms generally at remote areas and covers a wider, website production area is large, which will bring a lot of inconvenience to the daily production safety and property security, management, operation and maintenance.

Wind farm integrated security system function, resource sharing, business integration, such as the following needs to be improved in the following aspects:

1) the existing video monitoring system utilization rate is low, the degree of intelligence is not high, and there are still some key areas of the monitoring blind spot;

2) affected by the location of the location, the various wind farms facing the operational environment is very significant difference, the equipment may be encountered strong winds, dust, freezing and other harsh environment, resulting in high failure rate of equipment;

3) video monitoring system and production monitoring system without information interaction, when the operation or failure without video review;

4) inspection operation process, the personnel can not control the whole scene, there will be no safety standard operation, the work efficiency is not high;

5) the system is running independently, and the other auxiliary subsystems such as environmental monitoring, access control, access control system and fire control system can not be connected with the wind farm;

6) the system under normal circumstances require installation and configuration software and operating software, resulting in computer software and hardware redundancy, the system administrator of the business is not fine or omission of work;

7) there is no unified database, not in the internal information sharing, as well as the unified management and maintenance of system data;
Construction goal

Wind power generation has become China's third major power generation, to ensure the safe operation of the wind farm, to improve the power generation capacity and power generation efficiency of the wind farm, the economic development of China, social stability is of great significance. Due to fan the regional distribution of a wide range, on-site equipment operation patrol difficulty big, timeliness is poor, there is an urgent need to increase the corresponding technical measures to ensure the safety in production, and the original system bad definition, set low intensive degree, weak intelligence, there is an urgent need to build a adapt to modernization management of wind farm integrated monitoring and management system, in order to achieve the ultimate wind farm smart, efficient, safe and reliable operation. System with modern information technology as the support, network interconnection, information resources sharing, application functions, mainly to achieve the following goals:

1) covering the establishment of wind farm integrated monitoring and management system, for wind farm operation and equipment management in an all-round way, meet the wind farm monitoring room scene management, regional monitoring center of the global regulatory, management personnel mobile office needs.

2) on the video surveillance, intrusion alarm, the entrance management, environmental monitoring, fire alarm, intelligent control systems, such as integrated management, through a unified client to render, to ensure that the efficient use of personnel;

3) combined with the emergency response mechanism of the deployment plan, the rapid response and disposal of unexpected events, to effectively prevent security incidents, reduce and control the risk of accident;

4) make full use of video resources, monitor the operation environment of power generation facilities, regulate the operation, maintenance and repair process, ensure the stable operation of the wind farm;

5) through the existing information resources, the formation of all kinds of statistical reports, for the leadership of the decision-making;

6) using high-tech means, the first time to master the equipment is not online, job abnormalities and other fault information, timely troubleshooting, improve operation and maintenance efficiency, reduce operation and maintenance costs.

Solution

The overall topology of the system is shown below:

HD iDVR wind farm integrated security system is a set of hardware, software, network to an integrated security system, to iVMS-9800 software platform as the core, multi service fusion monitoring, in the main control room, the monitoring center can be on the front end system centralized monitoring and unified management, the safe production of the wind farm, and efficient operation to escort.

System can achieve the following functions:

1 HD video surveillance: the full access to 1080P and above HD video camera, enhance the quality of video and security level, to meet the requirements of the details of the monitoring (face, vehicle characteristics), support HD video storage;

2) intelligent analysis and recognition: 10 behavior detection, 3 anomaly detection, 2 feature recognition, 1 Statistical analysis;

3 auxiliary system integration: to achieve video surveillance, intrusion alarm, the entrance management, environmental monitoring, fire alarm, intelligent control system integration, each subsystem according to the plan for linkage;

4) three-dimensional supervision mode. The front (including wind turbines and step-up station site), wind power booster station control room, the regional center of the three vertical supervision, fixed network using C / s and B / S mode access, mobile network through the use of a hand-held terminals (mobile phones, tablet, etc.) regulation;

5) maintenance management: implementation of centralized monitoring of video monitoring system for monitoring, server platform, DVR, NVR, storage devices and other related equipment, the realization of the distribution in different segments of video equipment for monitoring and management.

Program highlights

1) intelligent: multi intelligent technology integrated application
2), the depth of integration of each security system:
3) reliability: improve the operation and maintenance management mechanism
4) security: an effective data security policy
