Power-saving rate verification method for main line type power-saving equipment in construction distribution system

Abstract

The invention discloses a power-saving rate verification method for main line type power-saving equipment in a construction distribution system. The method comprises the following steps of step (1), determining main electric equipment of a worksite; step (2), selecting a base period and a statistical reporting period; step (3), installing the main line type power-saving equipment, switching to a non-energy-saving mode and entering the base period; step (4), measuring the actual power consumption of each process in a measurement period within the base period; step (5), measuring the total powerconsumption of the base period; step (6), switching the equipment to an energy-saving mode, and entering the statistical reporting period; step (7), measuring the actual power consumption of each process in the respective measurement period within the statistical reporting period; step (8), measuring the total consumption of the statistical reporting period; and step (9), calculating the power saving rate of the product and the power saving rate per unit time in different process periods. According to the power-saving rate verification method for the main line type power-saving equipment in the construction distribution system provided by the invention, two indexes of the power saving rate of the product and the power saving rate of the measurement periods of different processes are usedas the verification indexes of the power saving rate of the main line type power-saving equipment in the construction distribution system, which can reflect the construction site condition and providea reference for the improvement of power quality in the distribution system.

Description

technical field [0001] The invention relates to the technical field of construction power distribution systems, in particular to a method for verifying the power saving rate of trunk-type power-saving equipment in the construction power distribution system. Background technique [0002] At present, the equipment that can effectively improve power quality and realize energy saving is mainly divided into two categories: terminal type and main line type according to the installation position in the power distribution system. Terminal equipment is equipment for energy saving and improvement for local or individual equipment or instruments. Since the loss of other parts in the power distribution system still exists, in the actual use of terminal equipment, it is possible that the overall Electric energy pollution or aggravated three-phase imbalance. Trunk-type equipment starts from the source of power loss, improves the power quality in the power distribution system as a whole, ...

Problems solved by technology

However, this method is only a verification method in an ideal state, and it is difficult to achieve the "four identicals" in the strict sense in actual production and life, especially in the infrastructure construction industry, due to the complex procedures and large time changes at the construction site , there are many types and quantities of construction equipment, and the power consumption of construction is greatly affected by the environment and construction procedures, etc., the "four identical" verification method is very demanding

Moreover, in the infrastructure construction industry, only using the "four identical" method to verify the power saving rate cannot truly reflect the power saving rate under different construction modes and processes
