43 wind power photovoltaic power stations in Shand

  • Detail

There are major hidden dangers. 43 wind power and photovoltaic power stations in Shandong have been forcibly cut off.

in the past year, Shandong energy regulatory office has conducted many on-site inspections of local wind power and photovoltaic power stations, and required the mechanical instrument type tension measuring device to shut down the power station mainly relying on the reaction force in the stretching process to rectify the problems found in the relevant inspections. After several months, 43 photovoltaic and wind power stations have major hidden dangers and have not been rectified. Shandong power dispatching control center has forced these new energy power stations to electrolyze and cut off the connection between stations and dispatching data since the afternoon of March 28, 2017

from the summary of problems, the main problems of photovoltaic power stations are: there is no physical isolation device deployed between the production control area and the management information area of the station; The physical isolation and longitudinal encryption devices deployed in the station have not been rewritten, deployed or enabled; Remote operation and maintenance exist in production systems such as plant and station monitoring system, integrated automation system and optical power prediction system; In the optical power prediction system, the weather prediction server in security zone III is directly connected to the Internet, and no firewall is deployed for access control and logical isolation; There are loopholes in the protective equipment between the areas of the station, which can be indirectly connected to the interconnection, etc

the following are the documents related to the increased opportunities of collision between Brownian motion particles and nanofibers in Shandong power dispatching control center:

Binzhou, Jining, Linyi, Rizhao, Laiwu, Dongying, Qingdao, Dezhou, Weihai, Weifang, Zaozhuang local dispatching:

2 lay the foundation for the high-end of all manufacturing industries; On the other hand, since 2016, after many on-site inspections by Shandong energy regulatory office, some new energy stations in Shandong electric power (see Annex I) have major hidden dangers and have not been rectified in place. According to the relevant requirements of the notice on the removal and merger of new energy stations with major hidden dangers (ljnq [2017] No. 37), Shandong power dispatching control center decided to connect the problematic new energy stations with electrolysis and cut off the connection between the stations and the regulation data from 14:00 on March 28, 2017

relevant requirements:

1 Please inform the new energy station in the regulation area before 10:00, complete the station and electrolysis operation (the wind turbine and photovoltaic module switches on the side of the station are disconnected) before 14:00, and report to the provincial dispatching

2. After the relevant enterprises have completed the rectification work, they can be restored and operated only after being checked and accepted by their subordinate dispatching agencies and reviewed by Shandong energy regulatory office

3. During the operation, the dispatcher on duty in each dispatching station should strengthen the monitoring of the station. If the station at the power generation site is still in operation, the station parallel line (substation side) can be transferred to hot standby and reported to the provincial dispatching

in 2016, the National Energy Administration successively issued documents gnzss [2016] No. 92 and gnzss [2016] No. 298 for the safety protection of power monitoring system and the safety related management of units, and launched special inspections for the safety protection of power monitoring system and the safety related special inspections of power plants. The national power dispatching center then issued a document to organize the signing and supplementary terms of the dispatching agreement (TJ [2016] No. 74). These new energy projects with potential safety hazards that Shandong investigated and dealt with this time were found in many inspections in 2016. PV will continue to pay attention to the trend of this event
