PV direct current simulation power supply with touch screen

Abstract

The present invention relates to a PV direct current simulation power supply with a touch screen. Two ends of the direct simulation power supply are respectively connected with a photovoltaic inverter, and the direct simulation power supply comprises a rectifying circuit and a master control assembly. The direct current simulation power supply also comprises a DC / DC convertor and a touch display assembly. The power grid, the rectifying circuit, the DC / DC convertor and the photovoltaic inverter are connected in order, the master control assembly is connected with the rectifying circuit and the DC / DC convertor, and the touch display assembly is connected with the master control assembly, and the touch display assembly is configured to control the rectifying circuit and the DC / DC convertor through the master control assembly to output alternate current, after rectification and direct current conversion, in the power grid to the photovoltaic inverter. Compared with the prior art, the PV direct current simulation power supply with a touch screen is provided with a resistor touch screen which is able to be arranged near the main circuit of the PV direct current simulation power supply, and is configured to design different display interface modules aiming at different modes, so that the PV direct current simulation power supply with a touch screen is convenient for operation and fast in man-machine interaction, etc.

Description

technical field [0001] The invention relates to a power control system, in particular to a PV DC analog power supply with a touch screen. Background technique [0002] At present, there are three ways to realize the display control part of the 100KWPV DC source on the market: LCD button combination control mode, PC control mode, and touch screen control mode. Compared with the liquid crystal button combination control method, the touch screen control method has a better human-computer interaction interface, high touch efficiency, and also provides higher safety performance, anti-bad weather performance and wear resistance. If only the PC control mode is used, and the PV DC source is far away from the PC, it is extremely inconvenient for the operator. [0003] For example, Chinese patent CN103746653A discloses a DC analog power supply with the characteristics of a photovoltaic inverter, which consists of a main circuit and a control system. The main circuit adopts a PWM rect...

Problems solved by technology

However, when the test range is large, the DC analog power supply cannot be adjusted uniformly, but can only be controlled independently; in addition, the DC analog power supply is not equipped with a touch control device, and the output UI characteristic curve cannot be displayed in real time, so the control is not convenient enough
