Embodiment 1

[0059] Embodiment 1: For grid fluctuations, by adjusting the line voltage regulator 101, the line voltage of the system is kept constant, such as 400V; the matching of electric loads is kept constant, and the state of resistive load and inductive load remains unchanged. Then, connect the produced power-saving device 106 in series in the main circuit; at this time, manually adjust the gear position of the power-saving device 106, for example, when there are three gears of A, B, and C, the three gears correspond to different voltages respectively working conditions. The active power under the operating conditions of the three gears is recorded respectively, and 3 sets of data are obtained, and these 3 sets of data respectively represent the power consumption of the present invention under the power-saving state. Then switch the operation mode of the power saving device 106 to the "bypass" state, and the bypass switch 105 is closed. At the same time, a set of data is recorded. We...

Embodiment 2

[0060] Example 2: For three-phase unbalance, three-phase unbalance is ubiquitous in industrial power systems, manifested as: unbalance between three-phase voltages, unbalance between three-phase currents, zero-sequence current Existence, etc., and some unbalanced degrees reach more than 20%, which seriously affects the overall efficiency and safety of the system's electric energy.

[0061] First, adjust the voltage of the power system to a stable state, such as 400V. In the power system, rationally allocate the load structure, put in a single-phase load electric heater with 3 kW, and connect a three-phase asynchronous motor with 11 kW. There are several lighting systems; at the same time, the produced power saving device 106 is connected in series in the main circuit, and any gear is kept unchanged; at this time, the power of the single-phase load is manually adjusted, and the operation of the power saving device 106 is recorded by the present invention state, the three-phase ...

Embodiment 3

[0062] Embodiment 3: Harmonic pollution is very harmful to the industrial production system. The present invention can effectively detect the harmonic control of the system, and can evaluate and optimize the harmonic control scheme. The specific steps are: connect the harmonic generating device 204 in parallel to the power consumption system, and observe the change of the harmonic value in the power-saving state and the bypass state by outputting different 2-25th harmonics. By comparison, it is determined whether the performance and quality of the power saving device 106 are good or bad.

Abstract

The invention relates to a high-low voltage on-line energy-saving verification system and method. The problem that the power-saving effect of the existing power-saving technology is good and difficultto classify is solved. The technical problems that the power saving rate is difficult to measure and calculate, energy saving treatment is difficult to evaluate and the like are solved, a main circuit and a control detection device are arranged, the main circuit is provided with a by-pass switch and a power saving device, the by-pass switch controls the power saving device to be connected or disconnected in the main circuit, and the control detection device detects power utilization parameters of the main circuit when the power saving device is connected or disconnected. The method can be widely applied to industrial power-saving equipment and power-saving equipment control strategy formulation.

Description

technical field [0001] The invention relates to a testing device for electrical performance, in particular to a high and low voltage online energy-saving verification system and method. Background technique [0002] At present, industry consumes more than 2 / 3 of the total electric energy, and the industrial sector is a particularly promising area for investment in energy saving and electricity saving. However, the equipment and processes used by many enterprises are still old equipment and processes used decades ago, and there is a serious waste of electric energy. The energy utilization rate of industrial products is only 32% to 34%. In the traditional concept, electricity bills are difficult to control and Savings, this is because the limitations of traditional technology cannot provide an effective comprehensive solution. [0003] With the application and popularization of various cutting-edge technologies, the electricity cost of enterprises can be effectively controlle...
