As shown in fig. 1, the present invention provides a debugging platform of a giant hydropower station monitoring system, which comprises a mobile debugging platform system and a production operation monitoring system;
when the mobile debugging platform system is physically isolated from the production operation monitoring system, joint debugging test is carried out; and when the mobile debugging platform system is accessed to the production operation monitoring system, switching the configuration library to finish debugging the production operation monitoring system.
In the embodiment of the present invention, as shown in fig. 2, the mobile debugging platform system includes a server and a switch;
the server is used for completing the functions of a database server, a data acquisition function and an operator station of a station layer in the production operation monitoring system;
the exchanger is used for forming an independent debugging network environment for joint debugging test with a local control layer in the production operation monitoring system.
In the embodiment of the invention, 3 displays are configured by 2 servers, MOS1 is configured by double screens, and MOS2 is configured by single screen. A movable debugging table is configured, a keyboard, a mouse and 3 displays are placed on a table top, and 2 servers and 2 switches are placed in a cabinet body below the table top.
Under the debugging environment, 2 workstations of MOS1 and MOS2 are configured, and MOS1/MOS2 are required to take the following functional tasks: an operator station function, a database server function, a data acquisition server function, and an advanced application server function.
In the embodiment of the present invention, as shown in fig. 3, the functional nodes of the production operation monitoring system include:
the operator station, namely a master node of a central control room operator monitoring and controlling power station;
a database server, namely a configuration library and a storage node of historical data;
the data acquisition server is a data node for acquiring the data of the local control unit and the data of the external equipment;
the dispatching communication server is a communication node which is used for carrying out data communication with national dispatching, network dispatching and ladder dispatching, uploading remote signaling data and remote measuring data and receiving remote dispatching commands and remote control commands;
and the application servers are computing nodes of the automatic power generation control application software and the automatic voltage control application software.
In the embodiment of the invention, the basic configuration of the production operation monitoring system needs to be provided with the following functional host nodes:
operator station OS1/OS 2: monitoring and controlling host nodes of the whole plant by operators in a central control room;
database server DB1/DB 2: a system configuration library and historical data storage nodes;
data acquisition server DS1/DS 2: collecting PLC data and other external equipment data nodes;
scheduling communications DCOM1/DCOM 2: the node is responsible for scheduling communication with a superior level, uploading remote signaling and remote measuring data and receiving remote adjusting and remote controlling commands;
advanced application server APP1/APP 2: and the AGC/AVC and other advanced application software computing nodes.
In the embodiment of the invention, a configuration library TESTDB for debugging a network environment is installed in a server; the database server is internally provided with a configuration library RTRDB for production operation.
In the embodiment of the invention, when the mobile debugging platform is incorporated into a production operation system, due to service priority, the mobile debugging platform has the bearing function of passing service scheduling, and only an operator station is left. The software configuration installed by all the nodes of the server workstation is maximally installed according to the computer monitoring system software. The functions enabled are enabled according to different configurations.
The main innovation point 1 of the invention is that each host node is designed in a peer-to-peer mode without a master mode, a host server is started and bears different functions by a service scheduling program according to different configurations in a configuration library, and each functional service host adopts a service queue mode and determines the priority of the functional service host by weight.
As defined by LCU data collection function configuration:
weight queue as service name acquisition host
LCU1 DS1：5；DS2：4；MOS1：3；MOS2：2；
The collection service of LCU1 can be assumed by one of DS1, DS2, MOS1 and MOS2, the priority of the collection service is arranged according to DS1- > DS2- > MOS1- > MOS2 in turn, when the service scheduling host detects that DS1 is offline (failed or not online), the collection service of LCU1 is taken over by DS2, and so on.
Therefore, in a debugging environment, the DS1 and the DS2 are not in the network, and the LCU1 acquisition service is borne by the MOS 1. When the mobile debugging platform is incorporated into a production operation system, DS1 and DS2 have higher priority than MOS1 and MOS2, so LCU1 acquisition service is borne by DS1, and DS2 is borne when DS1 fails.
The invention has the main innovation point 2 that when two independently operated systems (networks) are combined, the system can be realized only by switching the configuration library.
The MOS1 and the MOS2 are internally provided with a testing environment configuration library (TESTDB which is consistent with a production operation monitoring system configuration library RTRDB), and comprise a database, a picture and server function configuration contents, and the MOS1 and the MOS2 access the TESTDB in a debugging environment. The functionality of MOS1 and MOS2 within the TESTDB are configured as an operator station, a data collection server, a database server.
The production operation monitoring system is structured as shown in fig. 3, and includes various function servers such as system configuration data acquisition, a database, a high-level application, an operator station, scheduling communication, and the like. Within database servers DB1 and DB2 are configuration libraries (RTRDBs) for production runs. All server hosts access the RTRDB.
The mobile debugging platform is physically isolated from the production operation monitoring system and operates independently. Various tests and test works of debugging the LCU are carried out on the mobile debugging platform, and normal production operation is not influenced. During the debugging process, the picture, data point table and system configuration file of the debugging LCU need to be continuously improved.
And after the off-line debugging of the mobile debugging platform is finished, synchronizing the latest picture, the data point table and the system configuration file which are related to the debugging LCU in the TESTDB to the RTRDB. The system of MOS1 and MOS2 is shut down, the access configuration library of MOS1 and MOS2 is changed from TESTDB to RTRDB, the mobile debugging platform network is accessed to the production operation monitoring system network, and the system of MOS1 and MOS2 is started.
Based on the above system, the invention also provides a debugging method of the giant hydropower station monitoring system, as shown in fig. 4, comprising the following steps:
s1: performing joint debugging test on a local control layer of the production operation monitoring system on a mobile debugging platform;
s2: switching a configuration library, and updating the latest database and the latest picture in the mobile debugging platform after joint debugging test to a production operation monitoring system;
s3: and (4) accessing the mobile debugging platform system to the updated production operation monitoring system, starting a server, carrying out grid-connected test, and completing the debugging of the monitoring system.
