  • Frequent hydro-meteorological events caused by global climate change and human exacerbate activities, make the water resource problem more complicated. The increasing speed urbanization brings a significant impact on the city flood control and security, water supply safety, water ecological security, water environment safety and the water engineering security in China, and puts forward higher requirements to urban water integrated management, undoubtedly which become the biggest obstacle for water ecological civilization construction, thus urgent requiring an advanced methods to enhance the effectiveness of the water integrated management. The other fields of smart ideas point out a development path for water resource development. The construction demand of smart water resource is expounded in the paper, combining the philosophy of modern Internet of things with the application of cloud computing technology. The concept of smart water resource is analyzed, the connotation characteristics of smart water resource is extracted, and the general model of smart water resource is refined. Then, the frame structure of smart water resource is put forward. The connotation and the overall framework of the smart water resource represent a higher level of water resource informationization development and provide a comprehensive scientific and technological support to transform water resource management from an extensive, passive, static, branch and traditional management to a fine, active, dynamic, collaborative and modern management.

  • As we are approaching on the new paradigm for the water resource management. This is because there has been changed on the water resource environment. People want more water whenever they need, however increased absolute demand does not always meet the demand. Furthermore many water related social conflicts are getting increased in recent decades. Consequently, the emphasis of water policy became the core of water resource management. Therefore, research on the water resource policy should be diversified to derive prefer water management. In Korea this research has been done in recent, but within a very narrow view. We tried to evaluate the current status and suggest the direction of water resource policy.

  • Many errors are broken out when hydro power plants are operating connected to electric power system. To minimize ripple effects of accidents, a hydro power plant is separated by a circuit breaker consisting of each protection equipments. In this paper, I will analyze a cause of abnormal events of emergency stop and therefore I take measures and suggest solutions for similar cases.

  • Generator excitation system, supplying the voltage to power system, is controlled by various manners as aspects of power system. Previously excitation systems mainly used AVR(Automatic Voltage Regulator) and FCR(Field Current Regulator) to control voltage, but nowadays the excitation systems have the tendency to adopt AQR(Automatic Reactive power Regulator) and APFR(Automatic Power Factor Regulator) to do it so as to get into step with diverse requirements of power system and high digital technology. This paper presents which operation methods is effective for the equipment, according to increase the unmanned power station thanks to automation technic.

  • In establishing climate change adaptation strategies, the recent policy paradigm is changing from structural measures in the past to risk management. The establishment of water resource governance based on the participation and cooperation of various stakeholders is important in developing a climate change adaptation strategy. This paper identifies the limitations of Korea's water resource governance and seeks ways to improve the water resource governance for effective adaptation to climate change by examining the development process and current status of water management policies and water resource governance in Korea and major OECD countries.

  • Recently the development of small hydropower generation with using water pipes is revitalized by the water works facilities. However, when the tubine generator is in case of emergency stop by the internal and external accidents, it causes water hammer in water pipes and suspension of water supply. To prevent these problems of small hydropower generator, we has analyzed water supply patterns, installation position and water pipe systems.
