Debugging method and system for hydroelectric power station monitoring system

Abstract

The invention discloses a debugging method and system for a hydroelectric power station monitoring system. The debugging method includes: establishing a set of an upper computer system for a virtual power plant on a power plant side, wherein the upper computer system is used for simulating a monitoring system on the power plant side; integrally transplanting an upper computer platform on the power plant side to the upper computer system of the virtual power plant; setting up a temporary debugging network, connecting the upper computer system of the virtual power plant with a monitoring system on the centralized control side, and guaranteeing isolation with an existing running system; subjecting LCUs (local control units) on the power plant side to single testing and integral testing through the upper computer system of the virtual power plant; after integral testing is fully completed, applying for full stop of the whole site, integrally moving the upper computer system platform of the virtual power plant, completed in test back to the monitoring system on the power plant side, cancelling control over the upper computer system of the virtual power plant, realizing actual connection of the monitoring system on the centralized control side with the monitoring system on the power plant side, and verifying consistency of databases of the systems and accuracy of equipment control instructions. The debugging method and system is low in risk and influence, high in efficiency and complete in test.

Description

technical field [0001] The invention relates to a debugging method and a debugging system of a monitoring system of a hydropower plant. Background technique [0002] The traditional hydropower plant monitoring system debugging method is divided into three steps: first, complete the compilation of the databases, operation orders, lock-up library and calculation library of the upper computer on the centralized control side, then stop the power plant completely, and connect the centralized control side and the power plant side to the network. Modify the relevant database on the power plant side, check the basic switching function, data transmission and blocking function; then carry out a separate test for each local LCU (LCU: logic control unit logic control unit) on the power plant side and the centralized control side respectively; finally combined with the AGC test (AGC: auto generator control automatic power generation control), AVC (AVC auto volt control automatic voltage ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the commissioning process, the risk of equipment operation is high. The centralized control side is integrated into the existing monitoring system that has been put into operation before the on-site LCU test is carried out. Participating in the LCU causes huge operational risks;

[0004] 2. The debugging and modification are cumbersome. If the database needs to be modified during the debugging process, all servers must be modified synchronously. The workload is heavy and the process is cumbersome. The debugging personnel are prone to negligence, which invisibly brings risks to the debugging;

[0005] 3. There is a high risk of modifying the database of the host computer on the power plant side in the early stage. Since the power plant side system belongs to the operating system, the workload of the database modification in the early stage is heavy and the time is tight. Incorrectness will not only affect the follow-up test, but also may cause confusion in the monitoring system of the power plant side, and even cause the overall collapse of the monitoring system of the power plant side;

[0006] 4. It is very difficult to control the full stop time during the commissioning test. When the centralized control side is connected to the power plant side for the first time, it is necessary to apply for a full stop of the whole station. In the AGC and AVC tests, the local LCU control units of the whole plant are connected to each other. It is also necessary to apply for a full stop of the whole station during the commissioning test. Due to the existence of a large number of test items and the corresponding unpredictable situations, it is difficult to control the time of the full stop of the whole station
