Virtual instrument technology-based test method of power system test instrument and application thereof to integrated automatic device and synchronous detection device

Abstract

The invention discloses a virtual instrument technology-based test method of a power system test instrument and application thereof to an integrated automatic device and a synchronous detection device. In a structural system consisting of an upper computer and a low computer, the working performance of the upper computer and the low computer is brought into full play, functional expansion is further promoted and limited low computer resources can be fully utilized. The method comprises the following steps that: a test software module is selected in the upper computer according to a functional requirement; the upper computer partitions a program in the upper computer into a real-time program, a quasi-real-time program and a non-real-time program according to a partition program; the upper computer transmits the real-time program to the lower computer, the lower computer receives the real-time program and the real-time program takes over a digital signal processor (DSP) microprocessor and controls the DSP microprocessor to run; the upper computer makes calculation in alignment with the real-time program and the non-real-time program; the lower computer processes various external real-time information and calculates the real-time program; the upper computer transmits a calculation result to the lower computer according to a command of a transmission command program and exchanges data with the lower computer; and the lower computer makes response to the command of the upper computer and executes the command.

Description

technical field [0001] The invention relates to a test method for a power system test instrument containing virtual instrument technology, and an application method on a comprehensive automation device and a simultaneous detection device. Background technique [0002] Virtual instrument (Visμal Instrμctions) technology is the product of the combination of modern computer system and instrument system technology, and is an important technology in the field of computer-aided testing (CAT) today. It promotes the development of traditional instruments in the direction of intelligence, modularization, virtualization and networking. With the rapid development of the scale and technical level of the power system, in order to ensure the safe and reliable operation of the power system and obtain higher economic benefits, the types of parameters and items required to be monitored in production departments such as power plants and substations are also increasing. more and more.

Problems solved by technology

However, this deviates from the original intention of the virtual instrument (Visμal Instrμctions) technology, making it very inconvenient to upgrade and maintain special instruments, and has single functions and defects, such as not having enough space to store data, and not being able to display processing results in real time. The defects of the circuit in multiplication and division have to reduce the calculation accuracy, etc.
