Coal is the top fuel for power generation in both China and the United States. Its replacement is one critical method to mitigate the serious environmental impacts. Natural gas is associated with much less air pollution and is one of the most important alternative fuels. In the United State shale gas – one key type of unconventional natural gas – has become a disruptive energy resource during the...
As one of the most popular industrial network protocol used in the energy distribution field, the security, especially vulnerability of Modbus-TCP protocol has attracted great attentions from both academic and industrial field. Due to the Particularity of Modbus-TCP, traditional fuzzing framework for vulnerability detecting cannot work efficiently. To overcome this drawback, a special smart fuzzing...
A kind of monitoring and recording system of mechanical characteristics of high voltage circuit breaker is designed in this paper. The system that has the characteristic with microsecond single point acquisition speed and microvolt level amplitude resolution can collect information data of different mechanical characteristics of high voltage circuit breaker and automatic distinguishing data to fault...
The mechanical properties monitoring system of permanent magnet motor operating mechanism is developed base on the indoor 40.5kV vacuum circuit breaker in order to improve the security and reliability of power system. The high-precision linear displacement sensor is used to measure the stroke of moving contact, the angular sensor is employed to test the rotation angle of motor, and the hall current...
To access the batteries information in the process of charge and discharge in time, the article designed a monitoring system for the condition of storage batteries based on ZigBee. This approach used the chip of CC2430, which was integrated of AD converter, 8-bit strengthened MCU and wireless RF unit. The chip of CC2430 and the external circuits were made up the node of the star network. The temperature,...
In the chemical process, safety guarantee has become the hot issue with common concern. However, in current running-process, monitoring points are massive and the relation among them is complex, which lead to the trouble in guaranteeing the production safety. A new method based on matter-element analysis is put forward to guide the programming of monitoring points, which is composed of matter-element...
A new tire monitoring scheme is proposed in light of the defects of the existing tire pressure monitoring system. Parameters of various automobile tires can be monitored dynamically and transmitted to the driver meter through the network which consisted with ZigBee network and CAN bus. Then, auto tire failures early warning function is realized. Simulation and piracies proved that reliability and...
This paper studies the present state of water and soil loss in the Hubei province. Chinese scholars have analyzed the causes of water and soil loss, and pointed out that both natural factors and human activities are the root causes for these losses. The associated natural factors include the landscape, soil, groundwater and precipitation. Since the climate in this area is subtropical monsoon, heavy...
The lack of effective policy and law enforcement is a serious and pervasive problem in China and environmental protection is particularly affected. Low SO2 removal and operation rates at SO2 scrubbers were of specific interests of this paper. Through active capacity building and mobilization of local governments, significant progress was achieved with a new policy of desulfurized electricity price...
