为了精准量测典型田块作物的灌溉水量,需要设置计量设施,但由于末级渠道现场条件复杂,典型田块可能存在边界不清、形状不规则、与灌区面积不协调,以及种植作物、进水口不够单一等情况,即便选出了典型田块,但由于多为U形渠道,也不便于在... 为了精准量测典型田块作物的灌溉水量,需要设置计量设施,但由于末级渠道现场条件复杂,典型田块可能存在边界不清、形状不规则、与灌区面积不协调,以及种植作物、进水口不够单一等情况,即便选出了典型田块,但由于多为U形渠道,也不便于在末级渠道设置简易量水槛或采用标准断面量水。基于此,本文提出了一种在现场条件复杂的情况下在典型田块设置的超声波水表智能量测系统,该系统结构简单、便于维护,量测效果良好,适合复杂条件下的田间作物的灌溉用水计量。 展开更多

The study presents possibilities for reconstruction of electric power supply systems in Bulgarian Black Sea resorts and possibilities to use statistical methods in energy planning. The paper shows the use of classic statistical methods in combination with advanced digital measurement systems in order to obtain the correlation dependencies, nature of energy consumption and opportunities for energy forecasting. The main purpose of the study is to obtain statistical dependencies of the nature of power consumption and correlations between electricity consumption and ambient temperature in order to improve the accuracy of energy planning. The analysis includes application of energy management systems for proper energy planning, improving economical efficiency and reducing power and energy losses. 展开更多
