Abstract

The invention provides a three-phase data processing method, data acquisition equipment and a circuit control system. The method comprises the following steps: acquiring three-phase data corresponding to a target circuit; transforming the three-phase data based on a preset relational expression to obtain positive and negative sequence DQ components corresponding to the three-phase data, the preset relational expression being a matrix transformation expression among an active component of a three-phase parameter, a reactive component of the three-phase parameter and the positive and negative sequence DQ components of the three-phase parameter, and the three-phase parameter being a parameter corresponding to the three-phase data; and sending the positive and negative sequence DQ components to an external control device, so that the control device generates a control signal corresponding to the target circuit according to the positive and negative sequence DQ components. According to the method, the three-phase data can be directly converted into the positive and negative sequence DQ components through the preset relational expression, and subsequent control operation can be supported only by transmitting four variables for each data acquisition device, so that the data transmission efficiency is effectively improved, and the real-time performance and accuracy of subsequent control are improved.

Description

technical field [0001] The invention belongs to the technical field of data processing, and more specifically relates to a three-phase data processing method, data acquisition equipment and a circuit control system. Background technique [0002] In the prior art, in order to achieve circuit control, the parameters of the circuit are usually collected by the data acquisition device, and the collected parameters are sent to the control device through the communication bus, and the control device generates control parameters based on the received parameters. Signals to realize various controls of the circuit. [0003] Among them, in order to improve the control accuracy, you can choose to upload the instantaneous values ​​of various parameters. However, this method has high real-time requirements for the entire control system, which is difficult to meet in the actual application process. Therefore, the common solution in this field is to extract the active components and react...
