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

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0034] The present invention builds a set of monitoring systems that are completely equivalent to the side monitoring system of the B power plant in the A dispatching building 50 kilometers away from the power plant area, and are mutually backup monitoring systems to meet the basic technical requirements of remote centralized control.
[0035] Such as figure 1 As shown, the present invention includes the provincial regulation side, the power plant side monitoring system, the centralized control side monitoring system, the local LCU, the virtual power plant host computer system, the debugging network and several debugging switches. The power plant side monitoring system includes RTU and multiple one-way 104 protocol receivers. The monitoring system on the centralized control side includes multiple monitoring computers and a centralized control ...

The invention discloses a debugging method and a debugging system for a monitoring system of a hydropower plant. A set of virtual power plant host computer system is established on the side of the power plant, and the host computer system is used to simulate the monitoring system of the power plant side; and the monitoring host computer platform of the power plant side is transplanted as a whole to the host computer system of the virtual power plant; set up a temporary debugging network, the host computer system of the virtual power plant is connected to the monitoring system of the centralized control side, and ensures isolation from the existing operating system; the host computer system of the virtual power plant performs a single Test and overall test; after the overall test is completed, apply for a complete shutdown of the entire station, and relocate the virtual power plant host computer system platform that has completed the test to the power plant side monitoring system as a whole, cancel the control of the virtual power plant host computer system, and realize centralized The actual connection between the control side monitoring system and the power plant side monitoring system, and verify the consistency of the two databases and the accuracy of equipment control instructions. The invention has the advantages of small risk, small influence, high efficiency and complete 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 ...
