C4F7N gas mixture is considered to be a very promising SF6 replacement gas. In order to study the surface discharge characteristics of C4F7N gas mixture under the needle-plane electrodes, a fluid model of surface discharge was established using COMSOL Multiphysics for simulation, and the change patterns of electric field and photon flux during the development of streamer were obtained. By obtaining the change law of photon flux, it can provide the theoretical discharge. The simulation results show that the development process of streamer can be divided into three phases: streamer generation phase, streamer deceleration phase and streamer acceleration phase. During the whole process, the change trend of photon flux is basically consistent with the change trend of electric field. In the acceleration phase, the streamer gradually moves away from the needle electrode, the background electric field gradually decreases, and the frequency generated by the electron collision reaction weakens, leading to the slow development of the streamer, and the electric field and the photon flux at streamer head gradually decrease. In the acceleration phase, the streamer is converted from parallel to the plane electrode to perpendicular to the plane electrode, and the potential gradient becomes larger, leading to a faster development of the streamer and a gradual increase of the electric field and photon flux at streamer head.

With the increasing penetration of renewable energy in the power system, regulation capacity in the power system is highly demanded. To ensure the flexible operations of the power system, it is necessary to explore the potential flexibility regulation capacity and further promote the accommodation of the renewable energy. Under this context, a joint bidding strategy for battery energy storage in the regulation and energy electricity market is proposed in this paper. Firstly, a deep neural network method is used to predict the power system load, and reasonably divide the bid-accepted probability of flexible ramping products in the electricity market according to the predicted load. Then, an optimization model is proposed to offer the bidding strategies for battery electric storage providing flexible ramping products in the energy and regulation market. Finally, the effectiveness of the proposed model is verified by case studies and sensitivity analysis.

The characteristics of wide area coverage and deep coverage of 5G network can better promote the optimized operation of smart distribution network, while smart distribution network can provide a way to reduce cost and increase efficiency for 5G network operation. It is urgent to study the integration planning scheme of 5G network and smart distribution network to achieve benign two-way interaction between the two networks. This paper analyzes the integration of two networks from two aspects: 5G network improves the operation performance of smart distribution network and smart distribution network contributes to the promotion and construction of 5G network.

With the rapid development of Internet of Things technology, the remote monitoring technology has made rapid development. Based on ARDUINO NANO, ESP8266 and some sensors, A data monitoring system for internal suspended gin pole tower erection construction is developed. In the system, the digital drawing force sensor is used to measure the force status of external stay wire, support rope or internal stay wire of internal suspended gin pole tower erection in real time, as well as inclination sensor, and then the measurement value is transmitted to the mobile phone or PC terminal in real time, in which, the safe force range is set. When the measured drawing force is close to 80% of the safe force or other critical conditions, the alarm signal will be sent and the construction work must be stopped immediately. In this paper, the wireless transmission nodes, the wireless WIFI LAN base station, LAN communication mode and monitoring terminal are designed and implemented, respectively. In practice, there are some advantages for this system, such as good reliability, strong anti-interference ability, low cost, wide application prospects and practical value.

When a transmission line with high voltage shunt reactor is energized, the current DC offset will occur, which may cause a failure if the circuit breaker opens immediately after the closing operation. In this paper, a 500kV transmission line with high voltage shunt reactor is slected as the research object, and the electromagnetic transient simulation is carried out through the electromagnetic transient simulation software EMTPE to study the DC offset caused by closing of the circuit breaker of the long line with high voltage shunt reactor, including the DC offset caused by the single-phase closing of different phases. The simulation results show that for the transmission line with high voltage shunt reactor, it is reasonable that the temporary switching current doesn’t cross zero when closing the no-load line. This paper mainly analyzes the principle of this phenomenon and gives relevant suggestions.

In the operation and maintenance of smart distribution system equipment, in order to improve the intelligence level of inspection and significantly enhance the inspection efficiency and distribution network equipment management, it is critical to effectively identify and warn the partial discharge faults caused by insulation defects. In this paper, a feature extraction and identification method are proposed by experimentally simulating the partial discharges of typical defects inside the distribution network equipment. Firstly, different discharge models are built and the UHF sensor is used to obtain the partial discharge signals, and then the partial discharge statistical characteristics are calculated by analyzing features of the 2D and 3D partial discharge patterns. Based on various supervised machine learning algorithms, 3 typical defects are identified by the statistical characteristics using the classification learner. The results show that the selected statistical characteristics: the maximum amplitude of discharge, the average amplitude of discharge and the ratio of positive and negative half-period total discharge amplitude can well reflect the discharge characteristics of different defects and can distinguish between different types of discharges. At the same time, the identification accuracy of the three discharge types is high, which can achieve an accurate diagnosis of the fault types.

Compared with AC distribution network, DC distribution network has economic and technological advantages in many fields, but the access of high-density distributed power brings a huge challenge to the fault detection of the distribution network. The power electronic equipment contained in the DC distribution network is susceptible to the impact of inrush current, and a fast fault detection solution is urgently needed. In addition, influencing factors such as line distributed capacitance, synchronization error, and noise interference reduce the reliability of traditional fault detection schemes. A detection scheme based on wave impedance Minkowski distance is proposed to improve the existing technology. The program uses the Minkowski distance measurement to measure the correlation of wave impedance, and then identify internal and external faults. Theoretical analysis and simulation results show that the detection scheme based on Minkowski distance has high reliability and obvious advantages.
