    Practice and Reflection on Joint Operation Scheme of Water Projects of Pearl River Basin:Flood Control in 2022 by HUANG Feng, HOU Guibing, LI Yuanyuan

    Published 2023-01-01
    “…The joint operation scheme of water projects compiled year by year in the Pearl River Basin comprehensively considers the current situation of flood control in the basin and the practical experience of dispatching and continuously expands the water projects included in the scope of joint operation,which optimizes and adjusts the existing dispatching modes of water projects.It has now become an important non-engineering measure for real-time flood control operation.In June 2022,the Pearl River Basin experienced a catastrophic flood,second only to the one in 1915.Under the guidance of the basin joint operation scheme of water projects,and based on the flood characteristics and flood control situation,the Longtan Reservoir plays a core role,jointly operated with various types of water projects such as the reservoirs in the main and tributary rivers,flood storage and detention areas,and floodgates.It coordinates the overall situation of the river basin and fully taps into the flood control and storage potentials of water projects,successfully dealing with the 2022 flood.This paper sorts out the application of the joint operation scheme of water projects during the flood period in 2022 and analyzes the application mode and dispatching effects of the joint operation of water projects under different water inflow situations.Then,the deficiencies of the flood control joint operation scheme of water projects exposed during the flood period are summarized.Discussions are made on the optimization space of flood control operation mode of water projects with the Longtan as the core.Finally,the countermeasures and suggestions for the further improvement of the joint operation scheme of the Pearl River Water Project are proposed.…”

    AIRCRAFT POWER SUPPLY SYSTEM DESIGN PROCESS AS AN AUTOMATION OBJECT by B. V. Zhmurov

    Published 2018-03-01
    “…In this case, one of the results of EPS design will be a set of requirements for the devices and units of the EPS projected.In any case, the design process for EPS aircraft requires a lot of iterations that take into account the change in both the raw data and the constraints on the EPS elements and the design process itself.The traditional approach to the design of EPS aircraft, assuming the knowledge of the designer of dozens of GOSTs (State All-Union standards) and OSTs (All-Union standarts) regulating the design stages of EPS, as well as the existence of standard EPS structures, from which a specific choice is made, is practically impossible at present. The only way to consciously approach the problem of designing EPS aircraft and take into account all the requirements of the customer and the regulatory and technical documentation is its automation.Automation of the design of EPS aircraft as an optimization task involves the formalization of the object of optimization, as well as the choice of the criterion of efficiency and control actions. …”
