Problems solved by technology
[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a remote monitoring system suitable for use in situations where multiple machines are connected in parallel, with heavy loads, and power cuts. It solves the shortcomings of traditional generator sets such as scattered placement, difficulty in centralized management, difficulty in starting heavy loads, and switching of mains power generation and power failure.

Embodiment 2
[0030] Example 2, image 3 As shown, the integrated management device receives the signal to be connected to the load, determines the number of generator sets to be started according to the current operating system capacity and load capacity, and issues a command to start the corresponding generator sets. Each generator set is connected in parallel at the same time, and finally the load is closed. Switch, for the occasions where there is mains power, the mains power takes priority;
[0031] Figure 4 As shown, the control process of the integrated management device is as follows:
[0032] 1) The integrated management device scans for a load access request, if there is a load access request, go to step 2, if not, go to step 8;
[0033] 2) Judge whether the system has mains power. If there is mains power, turn on the mains switch and the mains power will load; if there is no mains, disconnect the mains switch and go to step 3;
[0034] 3) Judge whether the storage capacity is greater t...

The invention discloses a power generation and distribution intelligent monitoring system comprising a touch screen, an integrated management device, multiple power generator set control devices, multiple load monitoring instruments, a commercial power monitoring instrument, a power generator set air switch, a load air switch and a commercial power switch. RS485 asynchronous serial communication is performed among the integrated management device and the power generator set control devices, the commercial power monitoring instrument and the load monitoring instrument respectively. The touch screen and the integrated management device are connected by adopting an RJ45 interface. The integrated management device controls the power generator set air switch, the load air switch and a commercial power switch closing-switching brake according to monitoring data. Commercial power, power generation and power utilization situations are monitored in a concentrated way; the number of power generator sets in use and the generated power of each power generator set are automatically controlled in a remote way according to the size of electricity loads; the power generator sets are managed in a remote and parallel connection way so that parallel operation of any combinations of the power generator sets can be realized; and automatic grid connection and seamless switching of the power generator sets and commercial power can be controlled in the remote way.
Description
Technical field [0001] The present invention relates to a power generation and distribution monitoring system, in particular to a power generation and distribution intelligent monitoring system capable of realizing remote monitoring of the power generation and distribution system and continuously supplying power to the electric load. Background technique [0002] Due to the strong growth of electricity demand and the lagging power development, the contradiction between supply and demand has become increasingly prominent. Most areas of the country have power cuts during dry periods or high temperature periods. Generator sets are used as emergency backup power sources in power systems, industrial and mining enterprises, Public facilities, intelligent buildings, communication base stations and other fields have been widely used. The generator set control system can realize the functions of single unit control, data detection, status alarm, etc., and can perform three remote control ...
