Optic Network

High penetration level of distributed generation (DG) connected to distribution network makes the protection and control in the traditional distribution network face great difficulties, so this paper proposed a protection and control technology based on advanced feeder terminal unit (AFTU). According to DGs capability and load, the scheme divides the distribution network into several zones in advance, each of which can operate in island mode. Circuit breakers (CB) together with AFTU are installed at the beginning of feeder, the border of two zones and the point of DG connection. AFTUs interconnect with each other through the fiber optic network. AFTU detects the local electrical quantities in real-time and exchanges information with others through the fiber optic network. It can locate the faulted zone quickly to achieve fault isolation and island operation according to local and neighboring information. The reclosing of CB and the control of reconnection of DG are also designed. The case analysis illustrates the feasibility of the proposed distributed protection and control scheme.

Automatic Scheduling

Positron emission tomography (PET) is one of the commonly used scanning techniques. Medical staff manually calculate the estimated scan time for each PET device. However, the number of PET scanning devices is small, the number of patients is large, and there are many changes including rescanning requirements, which makes it very error-prone, puts pressure on staff, and causes trouble for patients and their families. Although previous studies proposed algorithms for specific inspections, there is currently no research on improving the PET process. This paper proposes a real-time automatic scheduling and control system for PET patients with wearable sensors. The system can automatically schedule, estimate and instantly update the time of various tasks, and automatically allocate beds and announce schedule information in real time. We implemented this system, collected time data of 200 actual patients, and put these data into the implementation program for simulation and comparison. The average time difference between manual and automatic scheduling was 7.32 min, and it could reduce the average examination time of 82% of patients by 6.14 ± 4.61 min. This convinces us the system is correct and can improve time efficiency, while avoiding human error and staff pressure, and avoiding trouble for patients and their families.
