Problems solved by technology

It can be seen from this that collecting the waveform data of the load is a waste of financial, material, manpower and time.
[0005] In addition, algorithm research also has high requirements for data. When the load types are complete enough, it is difficult to exhaustively list the multi-load waveform data in different scenarios. At the same time, a large amount of waveform data of different lengths is also required. It brings great difficulty to the data collection work.

Embodiment

[0076] The waveform data of the simulated power load needs a certain data base. Taking a family as an example, to simulate the load waveform data of the family, it is necessary to collect the waveform data of each load in the family when they work alone. processing, and then simulate the waveform data of the electric load, and finally store the simulated data in the database to provide experimental data for the load monitoring work. Assume that there are 5 kinds of loads in the family, namely air conditioner, electric kettle, TV, rice cooker, and refrigerator. For specific applications, the simulation is carried out according to the above 5 steps. The specific operation process is as follows:

[0077] Step 1: Load data collection. The experimenters use the ammeter to collect the waveform data of these five loads, and their current waveforms are as follows: Figure 2-6 shown.

[0078] Step 2: Data preprocessing. Such as Figure 7 , 8 As shown, taking TV and refrigerator as...

Abstract

The invention discloses a simulation method of a power load waveform. The method comprises the following steps: step 1, acquiring load waveform data; step 2, data preprocessing: dividing the data preprocessing into three links of phase alignment, amplitude modulation and data screening; step 3, typical data extraction: separating transient data and steady-state data containing a complete work cycle of the load by waveform observation and feature comparison; step 4, simulating single load current waveforms; and 5, simulating multi-load current waveforms. Load current waveform data with adjustable data length and controllable working scenes can be output, a database is provided for non-load monitoring work, meanwhile, great convenience is brought to data acquisition work of experimenters, a large amount of manpower, material resources, financial resources and time are saved, and a large amount of resources are saved for data acquisition work.

Description

technical field [0001] The invention relates to a simulation method, in particular to a method capable of simulating electric load waveforms. Background technique [0002] In recent years, my country's electricity demand has maintained a continuous high growth trend, and the State Grid has attached great importance to the monitoring of power loads. Therefore, research on power loads has been gradually carried out. However, the waveform data of loads is the basis for carrying out load monitoring research. [0003] At present, the method of obtaining these waveform data is that the experimenter enters the interior of the load user, and uses the electric meter to collect the waveform data of the load. The types of load waveform data collected include single load waveform data and multiple load waveform data. [0004] The waveform data of single load includes the waveform data of different loads in different modes, and the waveform data of multi-load includes the waveform data ...
