Problems solved by technology

The application of safety and stability control devices (referred to as stability control devices) in power systems is becoming more and more widespread, but there are many types of stability control devices, and most of them require secondary development. At each stage of production, engineering site and regular inspection, hardware module testing, system joint testing, software control logic accuracy testing, rationality and effectiveness testing of failure criteria, rationality testing and implementation of strategy table formulation are required. Correctness testing and other aspects of testing, so it is more troublesome; and the existing testing methods are not complete

Embodiment Construction

[0015] A general testing instrument for a safety and stability control device, which adopts interconnected dual CPU modules, wherein the internal serial ports are connected to each other; the left CPU module is connected in parallel with a switch input and output interface and an analog D / A converter; the other right end The CPU module is connected to the human-computer interaction interface. Wherein, the dual CPU modules are composed of ARAM, Flash memory, serial interface and peripherals. The internal serial port line interface is in the standard wave line data format. The output cycle of the analog D / A converter is 100 points per cycle. The dual CPU module is powered by a 5V power supply. The analog D / A converter is also connected with an anti-aliasing filter. The human-computer interaction interface includes buttons and LCD indicators.

[0016] The generation of the AC waveform is based on the signal generation technology of Direct Digital Synthesis (DDS). Using the si...

Abstract

The invention relates to the field of world power system, particularly to a general testing instrument for a security and stability control device. The general testing instrument comprises double CPU (Central Processing Unit) modules which are communicated with each other through an internal serial port line interface; the left end CPU module is connected with a switch input and output interface and an analog D/A (Digital-to-Analog) converter in a parallel mode; the right end CPU module is connected with a human-computer interaction interface. According to the general testing instrument for the security and stability control device, the small signal analog is output, the general testing instrument can be externally connected with a power amplifier element, different sources of data can be represented, the system condition can be actually simulated, and the general testing instrument can be suitable for the different stages and different content of testing of different stability control devices.

Description

technical field [0001] The invention relates to the world power system field, and specifically relates to a universal testing instrument for a safety and stability control device. Background technique [0002] With the development of grid construction. The application of safety and stability control devices (referred to as stability control devices) in power systems is becoming more and more widespread, but there are many types of stability control devices, and most of them require secondary development. At each stage of production, engineering site and regular inspection, hardware module testing, system joint testing, software control logic accuracy testing, rationality and effectiveness testing of failure criteria, rationality testing and implementation of strategy table formulation are required. It is more troublesome to test in many aspects such as correctness test; and the existing test methods are not complete. Contents of the invention [0003] In order to solve t...
