Abstract
In order to solve the existing noise reduction measures in substation is not comprehensive, and the lack of substation on-site interference measures, the monitoring system of partial discharge electromagnetic interference in ultrahigh voltage (UHV) substation environment is studied.

The results show that the electromagnetic interference monitoring system of partial discharge in the environment of UHV substation studied in this research can significantly improve the detection and localization of partial discharge, and can have more choices in determining the frequency band, which is helpful to improve the accuracy of time delay measurement so as to improve the accuracy of localization. The result of this research provides a good guidance for solving electromagnetic interference problems in UHV substations in China.
Research on Accounting Recognition and Measurement Related to Energy Management Contract
Authors: Jia Hui 
Published: March 2020

Abstract
The energy crisis of the 1970s prompted Western developed countries to explore ways to save energy by improving energy efficiency. The United States is the first to propose an energy management contract model that relies on market mechanisms to promote energy conservation. Its development has obvious bottom-up, market-driven economic characteristics. In the 1990s, the energy management contract mechanism was introduced into China, and its development has obvious top-down, policy-driven economic characteristics. Energy management contract is a relatively new business model. With the advancement of society, the form of energy management contract has gradually increased. At present, the accounting system for this type of business model has not been formed. Based on this situation, there are more and more problems in energy management contract. So far, China still lacks a unified accounting business accounting standard, and there have been many disputes in accounting practice. This has greatly affected the promotion and implementation of the new mechanism of domestic energy management contract, which inevitably has a certain impact on the development of the contract energy industry.

Published: March 2020

Abstract
The ballistic correction projectile uses several limited open-loop corrections to reduce the error of the projectile flight or the deviation of the projectile from the target due to the target movement, thereby reducing the projectile dispersion error and improving the hit rate. This paper draws on the existing advanced steering gear design, and improves the rudder blade airfoil and its plane shape according to the flight speed of the ballistic correction projectile (Mach 2). Through the analysis of degrees of freedom, a pair of limit devices have been added to the housing to make the servo system work more stable and efficient. At the end of the paper, the conclusion that the 5V voltage is better than the 3.3V power supply is obtained through the control experiment. The safety and reliability of the servo system are further verified by the anti-torque simulation of the cam mechanism and the anti-overload simulation of the servo motor.

Using the MMS communication protocol in IEC61850 Standard, the MMS communication module is designed on the CompactRIO platform of NI Company to realize the data interoperability between PMS2.0 and intelligent substation System.

Abstract
Deep convolutional neural networks have been widely used in image retrieval because of their powerful feature representation capabilities. Due to the high efficiency of hash space, many image retrieval algorithms based on deep hashing emerge. Aiming at the high correlation between the codes bits of hash code, this paper proposes a new end-to-end trainable deep hash algorithm to implement the feature grouping so that each code bit can express its unique partial image information. We add slice layers to reduce the repetitive expression of information and add the pairing loss to expand the difference between different categories of images and improve the recognition ability of the model for different categories. After training, we use the hierarchical search strategy to test the retrieval ability of the classification model. The mean average precision and recall of our algorithm can reach 87.5% and 92% respectively, which achieves great result in the related field and has important guiding significance for the future research of hash algorithm.

However, in actual work, the grounding wire is frequently used and the operation seems to be simple, which makes people feel paralyzed, and its importance is often neglected. Incorrect use often occurs, which reduces or even sometimes loses the safety of the grounding wire. Role, so must pay enough attention.

A new type of energy harvesting circuit is designed for the low output voltage of the photovoltaic cell, which can efficiently harvest the light energy in the transmission line. However, the vibration frequency of the transmission line is low, the structure of piezoelectric vibration energy harvester is designed by finite element method, the natural frequency is close to the vibration frequency of the excitation source, and the energy utilization ratio is the largest. The two energy collectors are impedance matched respectively in order to increase the energy output power of the whole system. The system is controlled with supercapacitor by energy management mode, which provides stable electric energy for load and realizes the sustainable self-power supply of wireless temperature sensor.
