The non-invasive load identification technology is a technology for analyzing detailed use conditions of household appliances in a user through user port voltage and current data, so that basic data are provided for power user bidirectional interaction such as demand response, intelligent power utilization, energy comprehensive service and the like. Compared with an invasive subentry metering mode, the method has the advantages of small investment, strong practicability and wide application prospect. At present, domestic user perception equipment taking non-intrusive load identification technology as a core mainly comprises a non-intrusive load identification terminal, a multifunctional load identification table, a load identification intelligent air switch and other product forms. Urban and rural resident interactive demonstration projects taking a non-intrusive load identification terminal and a multifunctional electric meter as main forms are already applied to trial-run or developed on a large scale in a plurality of provinces and cities in China.
After research of nearly ten years, numerous scholars and research institutions in China successfully apply and develop the technology into products, and by relying on the key special item 'urban user and power grid supply and demand friendly interactive system' of Jiangsu 863, installation and application of non-home-entry terminals are carried out in Suzhou and Hezhou areas, and the resident demand response demonstration project with the largest user scale in the world is implemented. Under the influence of the test point effect of Jiangsu, other provinces and cities in China are beginning to test non-invasive technologies.
The digital test system platform of the non-intrusive load sensing module directly sends a recorded waveform file (meeting the requirement of the Commride standard format defined by IEEE and containing voltage and current information) of the running of an electric appliance to a receiving interface corresponding to the load sensing module in a digital quantity mode, and independently detects the load sensing module in a mode of collecting a load sensing result.
Based on the load identification detection platform generated under the scenes, digitized power utilization information is transmitted to the MCU development board in a network port mode mainly through detection software, then the MCU development board sends the digitized power utilization information to the designated identification module through a serial port, the MCU collects feedback of the identification module and forwards the feedback to the detection software.
Since the MCU has limited performance (about 5 ms/packet) and can only maintain one TCP connection, the detection software should control the communication rate (about 5 ms/packet) with each MCU and only establish one TCP long connection, and communication with the same MCU can only use this connection all the time, thus limiting the performance of the whole system.
