Unified addressing-based comprehensive monitoring wind and water power monitoring method of large-lag system

Abstract

The invention discloses a unified addressing-based comprehensive monitoring wind and water power monitoring method of a large-lag and great inertia system. A comprehensive monitoring system used in the unified addressing-based comprehensive monitoring wind and water power monitoring method comprises comprehensive monitoring background software, a server which is used for carrying out comprehensive monitoring, an exchanger and a controlled PLC (Programmable Logic Controller). In comprehensive monitoring, a wind and water power monitoring module is constructed, monitors of all devices and sensors related to wind and water power are placed in the wind and water power monitoring module, and meanwhile, all related background parameters are placed in the wind and water power monitoring module; the wind and water power monitoring module is used for carrying out unified addressing on all digital inputs, digital outputs, analog inputs, analog outputs and fixed parameters; the wind and water power monitoring module is an opened platform, and a control strategy of the wind and water power is compiled in the platform; through the unified addressing, control on the wind and water power of a large-lag and high-inertia system is easily realized in a comprehensive monitoring level, the advantages of comprehensive monitoring are expressed, and parameter adjustment of the control strategy and comparison and selection of the control strategy can be easily controlled; through the unified addressing, monitoring on all devices of a whole station can be easily realized, so that multiple complicated control strategies can be easily realized.

Description

technical field [0001] The invention relates to a wind hydropower control method applied to a large-lag large-inertia system, and belongs to the monitoring field of comprehensive monitoring. Background technique [0002] Traditional large-delay and large-inertia systems such as figure 1 As shown, taking the subway as an example, its wind, water and electricity are monitored through PLC, and the control strategy is realized in PLC. The existing problem is that it is inconvenient to modify the control strategy, and it is even more inconvenient to replace the control strategy. Moreover, unlike comprehensive monitoring, PLC brings together a large number of professional , has the advantage of a large amount of data. It is difficult for PLC to adjust the control strategy according to information such as indoor and outdoor temperature and humidity, passenger flow, planned driving interval, passenger flow, holidays, etc. In addition, it is also difficult for PLC to store a large am...

[0002] Traditional large-delay and large-inertia systems such as figure 1 As shown, taking the subway as an example, its wind, water and electricity are monitored through PLC, and the control strategy is realized in PLC. The existing problem is that it is inconvenient to modify the control strategy, and it is even more inconvenient to replace the control strategy. Moreover, unlike comprehensive monitoring, PLC brings together a large number of professional , has the advantage of a large amount of data. It is difficult for PLC to adjust the control strategy according to information such as indoor and outdoor temperature and humidity, passenger flow, planned driving interval, passenger flow, holidays, etc. In addition, it is also difficult for PLC to store a large amount of historical data for statistics and comparison. , calculation, in order to predict the best control strategy, but the subway wind and hydropower monitoring involves the monitoring of complex related equipment and the measurement of sensors, and the traditional comprehensive monitoring is used for monitoring, and there is a problem that it is difficult to manage these devices
