After large-scale photovoltaic (PV) and wind power integration with the national grid, the island grid detection is a crucial technique that identifies when a grid should be considered as dead. This logic is built in an IEC61850 grid controller which mainly depends on the bus bar scheme and fault type. It becomes more complex when the ½ circuit breaker scheme is utilized. The lack of communication redundancy causes island mal-operation due to the substation's DC supply failure. In order to avoid such mal-operation discrepancies, this paper investigates the conventional islanding detection method. Then, an advanced IEC61850 grid controller 2oo3 architecture is proposed for islanding detection, based on SAS redundant communication which improves reliability. However, even if there is an interface communication failure, the power plant control center can still detect the islanding through the proposed IEC61850 grid controller and SCADA IEC60870-5-101/104 gateways integration. This method has the tendency of full supervision of the entire grid and perfect logical judgment by plant operation staff. This feasible and the proposed redundant communication architecture can play a decisive role for power system network stability in order to avoid system blackout.

As a kind of renewable clean energy, the constant access of wind power to power grids is bound to have a great impact on the power system. Based on the grid structure in Fuxin, this paper will state the difficulty of peak regulation and the matter of wasting wind power caused by the large-scale wind power integration and put forward some reasonable methods for using the wasting wind power in the heating in winter. The relevant results indicate that capacity of local consumption of wasting wind power can be improved. Under the circumstances, it can be conductive to solve the problem of wasting wind power results from the difficulty of peak regulation as well as inspire the power system planners.

Анализируются возможности использования локальных беспроводных сетей широкополосного доступа в системах управления спасением людей в чрезвычайных ситуациях. Рассматриваются методы локализации пользователей, оказавшихся в опасных условиях, а также способы повышения доступности информации о них для передачи в центр управления спасением и уровня информированности самих пользователей о планах центра по их спасению. Предлагается оригинальное решение, позволяющее выполнять локализацию поэлементно, т. е. в помещениях и на отдельных участках области обслуживания системы. Показано, что решение может быть успешно использовано для организации сетевой инфраструктуры объектовой части глобальной экспертной системы, обеспечивающей доступ массового абонента в любое время и в любом месте к услуге индивидуализированного управления спасением абонентов при возникновении чрезвычайной ситуации природного или техногенного происхождения. Представлены методы повышения устойчивости сети, в частности метод построения одноранговой ad-hoc-сети с использованием коммуникаций устройство-устройство. The article analyzes the possibilities of using local wireless broadband access networks in emergency management systems for rescue people. Methods of localization of users in dangerous conditions, ways of increasing the availability of information about them for the rescue control center, as well as the level of awareness of the users themselves about the plans of the center for their rescue are considered. It is proposed the original solution, that allows localization to be performed element by element, i.e. in rooms and certain areas of the system service area. It is shown that the solution can be successfully used to organize the network infrastructure of the facility part of the global expert system, which provides mass subscriber access at any time and in any place to the service of individualized management of the rescue of subscribers in case of natural or man-made disasters. Methods for enhancing network stability are presented, in particular, a method for constructing a peer-to-peer ad-hoc network using device-to-device communications.

Multi-physics coupling analysis is one of the most important fields among the analysis of nuclear power plant. The basis of multi-physics coupling is the coupling between neutronics and thermal-hydraulic because it plays a decisive role in the computation of reactor power, outlet temperature of the reactor core and pressure of vessel, which determines the economy and security of the nuclear power plant. This paper develops a coupling method which uses OPENFOAM and the REMARK code. OPENFOAM is a 3-dimension CFD open-source code for thermal-hydraulic, and the REMARK code (produced by GSE Systems) is a real-time simulation multi-group core model for neutronics while it solves diffusion equations. Additionally, a coupled computation using these two codes is new and has not been done. The method is tested and verified using data of the QINSHAN Phase II typical nuclear reactor which will have 16 × 121 elements. The coupled code has been modified to adapt unlimited CPUs after parallelization. With the further development and additional testing, this coupling method has the potential to extend to a more large-scale and accurate computation.

UNSTRUCTURED In a matter of months, COVID-19 has escalated from a cluster of cases in Wuhan, China, to a global pandemic. As the number of patients with COVID-19 grew, solutions for the home monitoring of infected patients became critical. This viewpoint presents a telesurveillance solution—Covidom—deployed in the greater Paris area to monitor patients with COVID-19 in their homes. The system was rapidly developed and is being used on a large scale with more than 65,000 registered patients to date. The Covidom solution combines an easy-to-use and free web application for patients (through which patients fill out short questionnaires on their health status) with a regional control center that monitors and manages alerts (triggered by questionnaire responses) from patients whose health may be deteriorating. This innovative solution could alleviate the burden of health care professionals and systems while allowing for rapid response when patients trigger an alert.
