Smart substation construction planning smart grid first edge
Even though the five-way system was popularized and popularized, for a long time, the substation monitoring system was always in a 'supporting' position. Xu Junbing, director of industry and marketing of Shenzhen Zhongxing Liwei Technology Co., Ltd., said: 'A lot of times the substation remote monitoring system is just a device that can be used very well and can't be used or used. 'Until the Twelfth Five-Year Plan' the concept of 'smart grid' was proposed (the concept development of the smart grid participates in Table 1), and from 2009 to 2010, it is planned as a pilot phase of smart grid planning, and it will gradually enter the comprehensive construction phase. Substations have truly set off application innovations. Zhongxing Liwei Xu Junbing emphasized: 'Substations need to be intelligent and substations should be left unattended. Data and video of various substations must be sent to the monitoring center in a timely, accurate, and clear manner. Read at any time; duty personnel can not stare at the screen for 24 hours, then the video screen abnormalities, abnormal data, abnormal access control and other alarm information must be sent to the monitoring center in a timely manner; once found anomalies, maintenance personnel must immediately rush to the scene, touch To intractable diseases, it is necessary to use the wireless individual soldier system to transmit live video and video information to the monitoring center. Experts from the monitoring center will consult together and even connect to video conferences, which will be jointly consulted by experts from multiple places.
It can be seen that the national smart substation construction plan proposed by the 'Twelfth Five-Year Plan' not only raises higher requirements for the substation monitoring system, but also indicates that the 'five remote' monitoring system must also be fully intelligent, thus providing the entire substation. The intelligentization provides strong protection. At the same time, substation monitoring systems must incorporate systems such as access control, security precautions, and alarms to create a full range of intelligence. This is undoubtedly a challenge to the reform of substations.
Smart Grid Exposed Substation Upgrade
As we all know, the substation is the core node of the power transmission and transformation network, but due to its large number and wide geographic distribution, it is difficult to manage and maintain. Substations mostly use remote control, remote signaling, telemetry, remote adjustment, and remote viewing as the main management tools. However, with the advent of the 'smart grid', centralized networking, high-efficiency intelligence, and business integration have gradually become the new direction for the development of substation management. Below, we will analyze in detail how the 'smart grid' has brought a new look to the substation.
'IQ' raises new appearance in substation
The introduction of 'smart grid' makes the concept of 'smart substation' more transparent. As Zhang Yanchao, a senior consulting engineer in the Solution Department of Suzhou Keda Technology Co., Ltd. puts it: 'The smart grid is built to build a reliable, safe, economical, efficient, environmentally friendly, safe-to-use power grid system. The true integration of systems (perimeters, access control, warning systems, etc.) is an important part of the smart grid. '
Our cleaning Constant Force Actuator, cleaning Force Control System, cleaning active contact flange have many advantages over other grinders. It can realize flexible grinding, quick repsond to surface changing, and instant adjusting. Traditional mechanic hand lacks flexibility, and it is not easy to adjust, hard to realize mass production.
