Embodiment

[0050] The intelligent power device in this embodiment is such as Figure 15 As shown, it consists of 4 parts, including the main CPU module, connection backplane, sub-CPU-analog sampling module and sub-CPU-I / O module. The following describes the data interaction mode between the main CPU and sub-CPU and the internal simulation of the sub-CPU module. Signal, I / O signal, control signal mutual transmission relationship.

[0051] The main CPU module is the control center of the device, responsible for the identification of sub-CPU modules, data gating and data switching of sub-CPU modules, system protection criteria, interaction with HMI, and management of all resources inside the device. The connection backplane is used to transmit the information collected by each sub-CPU to the main CPU through the communication bus, and provide working power for each module.

[0052] There are CPU, A / D chip, multi-channel switch, analog signal adjustment circuit and n-channel TA, TV transfor...

Abstract

The invention relates to an intelligent electrical device, and belongs to the technical field of intelligent power distribution stations. The intelligent electrical device has the advantages that I / O (input / output) inserts and sampling inserts are not separated on a backboard, and card information are exchanged through connection among modules, so that the objective of mixed inserting of the I / O inserts and the sampling inserts can be achieved, and the number of the inserts can be flexibly set according to project needs; programmable logic controllers are introduced into slave modules, so that operation pressure of a programmable logic controller in a master module is relieved greatly, and system expansibility is remarkably enhanced; the programmable logic controller in the master module does not participate in early-stage data processing, so that system resources are reduced; in occasions with large external extension demands, a low-level processor can be considered so as to reduce system cost moderately.

Description

technical field [0001] The invention relates to an intelligent power device, which belongs to the technical field of intelligent distribution stations. Background technique [0002] The integrated acquisition and control devices in the integrated control system of distribution stations are generally installed in conventional switching stations (stations), outdoor small switching stations, ring network cabinets, small substations, box-type substations, etc. Acquisition and calculation of position signal, voltage, current, active power, reactive power, power factor, electric energy and other data of switchgear, communication of each device, opening and closing operation of switches, and realizing fault identification of feeder switches , isolation and restoration of power to non-faulty areas. as attached figure 1 As shown, take a small switching station with 12 lines as an example. The collection and control device is responsible for collecting the binary input and analog q...
