A detection system and detection method for substation integrated measurement and control host

Abstract

The invention discloses a detection system and a detection method for an integrated measurement and control host of a transformer substation. The detection system for the integrated measurement and control host of the transformer substation comprises a control main module, and at least two analog quantity output sub-modules. Each analog quantity output sub-module is connected with the control mainmodule, a power supply grid and one analog quantity local sub-module. The system further comprises at least two switching quantum modules. Each switching quantum module is connected with the controlmain module and one switching value local sub-module. Each analog quantity output sub-module is used for providing voltage and current for the analog quantity local sub-module connected with the analog quantity output sub-module through power supply of the power grid and according to analog quantity control information. The waveform of the voltage and current provided by each analog quantity output sub-module for the analog quantity local sub-module connected with the analog quantity output sub-module is same as the frequency of the power supply voltage provided by the power supply grid for each analog quantity output sub-module, and phases are synchronous. According to the invention, the requirement for an external time synchronization device can be reduced, and the test cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a detection system and a detection method for a substation integrated measurement and control host. Background technique [0002] The smart substation adopts the integrated measurement and control host of the whole station and the local protection mode. The measurement and control adopts the "two layers and one network" system architecture, which is composed of the interval layer, the station control layer and the station control layer network. The digital local module is connected with the primary equipment. connect. [0003] The whole station integrated measurement and control host replaces the mode of configuring different measurement and control devices in different intervals of the smart substation. The whole station is equipped with two sets of integrated measurement and control hosts to realize all interval measurement and control functions, namely remote signaling, t...

Problems solved by technology

The third-generation intelligent station adopts an integrated measurement and control scheme. Each interval has a measurement and control sub-machine responsible for data collection and uploading. Two sets of measurement and control hosts realize measurement and control functions such as remote signaling, telemetry, remote control, and remote adjustment. There is a big change, the online test of a single measurement and control sub-machine and the measurement and control host and the test system of the intelligent station measurement and control device. Measurement and control requirements require multiple outputs to simultaneously increase the amount of testing for multiple measurement and control sub-machines

[0005] Simultaneously increase the amount of multiple devices In the traditional test scheme, each device needs to add a synchronization device, which greatly wastes resources and increases costs
