Distributed type power supply parameter monitoring method and system based on GPRS/GIS

Abstract

The invention relates to a distributed type power supply parameter monitoring method and system based on a GPRS / GIS. The system comprises a remote collection terminal, a GPRS / SMS data communication unit and a distributed type power supply monitoring center, and the remote collection terminal is in data communication with the distributed type power supply monitoring center through the GPRS / SMS data communication unit. The method and system can finish integration of GIS spatial data and telemetry and telecontrol relational data, and the target of the distributed type power supply parameter online monitoring system is achieved; the system regards a public wireless data communication mode as a data transmission means, telemetry and telecontrol are achieved with a low cost, and meanwhile the system flexibility and adaptability are represented; the system achieves online detection on distributed type power supply parameter change situations, working states of distributed type power supplies can be monitored at any time in a remote monitoring mode, the whole distributed type power supply system can be in the optimal working state with assistance of an auxiliary decision and analysis system, and the monitoring function is played to the maximum extent.

Description

technical field [0001] The invention relates to the field of distributed power monitoring, in particular to a GPRS / GIS-based distributed power parameter monitoring method and system. Background technique [0002] Distributed power generation refers to small generator sets designed and installed at or near users in order to meet the needs of some special users and support the economic operation of existing distribution networks, mainly including wind power, photovoltaic power, fuel cells and gas Various forms such as combined cooling, heating and power supply. The distributed power supply currently developed has certain advantages in reducing environmental pollution and reducing the cost of end users. At the same time, it has the characteristics of high efficiency and flexibility and meets the requirements of sustainable energy development. Therefore, as the proportion of distributed power sources in the power system gradually increases. After it is connected to the grid, i...

Problems solved by technology

The transmission efficiency of this communication scheme is not high, and after multi-layer data aggregation, the reliability is also greatly affected

[0004] The management software lacks GIS system to provide geographic information support, and the location of the faulty equipment cannot be intuitively displayed in the system after the distributed power supply fails, which is inconvenient for maintenance personnel and system management

At the same time, the current monitoring system lacks the function of adding and deleting equipment, which is not convenient for users to modify and reconfigure detection equipment on site

[0005] In the prior art, GPRS communication needs a public network IP with a fixed address. The public network IP resources are less, and the application and maintenance costs are high, which is not convenient for users to use.

For industries with centralized management of network IP resources such as electric power, petroleum, and chemical industry, the acquisition and use of server public network IP are greatly restricted
