Polaris Smart Grid Online: Traditional video surveillance is widely used in the power industry, including deployment of video surveillance in unattended substations, safety production, transmission lines and other fields. Among them, the monitoring application of unattended substations is particularly typical, with significant power system industry characteristics. Substations are the hub of the power grid and are also an important target for power safety management. Establishing a networked video surveillance system in unattended substations can help the power sector to effectively save human resources and improve safety management efficiency.
With the development of high-definition and security integrated technologies, this application is showing a clear trend of high-definition and security integration.
In deployment, each substation conducts planning and deployment of monitoring points according to the number of objects that need to be monitored and the functions that need to be completed. Each monitoring point is centered on a high-definition network camera. It is connected to alarm devices such as magnetic, infrared, smoke, and temperature sensing through corresponding interfaces, and connects audio devices such as pickups and loudspeakers through the audio input and output interfaces. HD network cameras are used to capture images of substation monitoring sites inside and outside, including gates, perimeters, computer rooms and substations. The access control system is deployed at the gate of the substation and can register internal employees' access. It can send an alarm signal when someone illegally invades. The smoke and temperature sensing equipment mainly detects the internal environment temperature, smoke and dust, and prevents the occurrence of fire. When there is a warning, it can send an alarm signal in time.
Infrared radiation alarms are mainly deployed in surrounding areas of substations. When someone climbs over the wall and enters the station, infrared alarms will be triggered.
These alarm devices are connected to the video encoder through alarm monitoring. When an alarm occurs, the linkage can be performed through the management platform. In the dispatch center, sound and light alarms, image switching, and video recording control can be implemented.
The pickups and loudspeakers are audio intercom devices, which can be connected to monitoring systems through HD network cameras to implement voice intercoms between the dispatch center managers and substation field personnel, thus realizing remote scheduling of monitoring points by the dispatch center. At the same time, this function can also realize remote maintenance guidance for substation equipment, thereby shortening the time for solving problems and reducing manpower and cost. In addition, the monitoring and management platform can also be integrated with the existing substation power environment monitoring system. The environment monitoring system collects operational faults such as transformers, lines, switches, circuit breakers, and instrumentation as well as abnormal operating environments such as voltage, current, and temperature. Can trigger the video surveillance system linkage, in the dispatch center for sound and light alarm, image switching and video control.
As an intuitive, efficient and timely remote communication tool, videoconferencing has become an important part of the information technology application of the power industry. It includes various types of video conference derivative applications such as remote consultation, remote training, and remote collaboration. The power company's management, training, collaboration, emergency and other aspects.
Convening various types of work conferences remotely through the Internet is a typical application of videoconferencing in the power industry. Based on this application, business leaders can communicate face-to-face with relevant leaders of subordinate branches and branch offices without leaving their homes. Scenarios will no longer appear, saving time and costs for the organization of the meeting and improving the efficiency of communication and management.
Talents are the source of power for sustainable development of electric power companies. To improve overall competitiveness, it is necessary to constantly improve and perfect the talent training mechanism of enterprises.
Due to the large number of organizations in the power companies and their decentralization, organizing large staff training is a considerable headache for them. However, based on video conferencing, remote video training for hundreds of people and thousands of people can be easily organized. This not only helps companies significantly reduce training expenses, but also more importantly, increases training frequency and achieves more sharing.
All remote conference and training processes, as well as supporting materials such as meeting materials and training courseware, can be simultaneously broadcasted to the company's internal network. Employees can perform selective real-time viewing according to their own authority. Moreover, the above content can also be recorded synchronously through the recording and broadcasting functions of video conferences and posted on the Internet for on-demand learning by employees.
