김종안,우주희,최인규,Kim, Jong-An,Woo, Joo-Hee,Choi, In-Kyu Korea Electric Power Corporation 2015 KEPCO Journal on electric power and energy Vol.1 No.1
A digital Governor (GOV) has been developed for being used for a Francis hydro turbine, and the validity of the GOV has been tested. As for the hardware system for the GOV, we purchased a basic digital control system that already had proven its reliability in the power industry. We developed a set of new GOV software and integrated it with the hardware system, and finally verified the performance of the whole GOV system. For the human-machine interface (HMI), we configured and implemented appropriate graphic interfaces for the turbine operations. This paper describes the major GOV control functions, approaches we took in developing the GOV control logics, and the validity tests and the results.

In the past two to three years, the regional food plan is rapidly spreading to 46 places, and the government plans to spread to 100 local governments by 2022. Although agricultural extension agency are responding to various forms, there are insufficient studies on actual conditions analysis and future plans. This study examines the contents and level of local food policy by using monitoring indicators that reorganized 37 actions of Milan policy agreements into 31 actions in 4 categories for 8 local governments that established food plans with government support in 2018. This study analyzed the function and the role sharing system between the agricultural administration office and the agricultural technology center, and suggested the role and task of the agricultural technology center for activating the food plan. As a result of the monitoring, the main tasks of the Agricultural Technology Center to promote the food plan are:food plan education for farmers, local food and urban farming-based community kitchens, cities and rural linked community-supported farming, food life education and rural experience education, strengthening of planned production system, operation of local certification system, suggest of fair price and appropriate income standards, and operating the food information platform. The functions and roles of the Agricultural Technology Center were less importance in the Rural Food Plan and the Urban Food Plan, whereas the Agricultural Technology Center was divided between the Agricultural Administration, Agricultural Technology Center, and Foundation. In order to cope with the spread and advancement of the food plan, the rural guidance project should be shifted from the center of ‘extensions for special farmers’ to the ‘'sustainable food system for the whole nation’.
