Description

Static reactive power compensating equipment with real-time monitoring, demonstration, record wave energy

Technical field

The utility model relates to a kind of power system reactive power compensation arrangement, particularly has the static reactive power compensating equipment of real-time monitoring, demonstration, record wave energy.

Background technology

Along with the extensive use of static reactive power compensating equipment, traditional put into operation, aspect days such as use, accident analysis and emergency maintenance are inadequate, main outstanding behaviours is:

1. when putting into operation, can not in the very first time, intuitively understand the variation of fielded system parameter and SVC system waveform parameter.

2. do not possess harmonic wave check and analysis ability before and after putting into operation.

3. it is not directly perceived that the quality of power supply before and after putting into operation is improved effect comparison.

4. unusual waveforms information is not recorded ripple, and failure analysis report can not quick and precisely be provided, and repairing brings uncertainty to emergency.

Summary of the invention

At deficiency of the prior art, the utility model provides a kind of static reactive power compensating equipment that solves the real-time monitoring of having of prior art problem, demonstration, record wave energy.

For achieving the above object, the utility model is achieved through the following technical solutions:

Static reactive power compensating equipment with real-time monitoring, demonstration, record wave energy, it is characterized in that: this device comprises regulator cubicle, thyristor valve group, bank of filters, wave recording device, wave recording device is embedded on the regulator cubicle in the static reactive power compensating equipment, voltage transformer APT, BPT in the regulator cubicle, CPT; Current transformer ACT, BCT, CCT; Current transformer Dct, Ect, Fct and FC filter current transformer insert respectively on every road input channel of a, b, c, d, e, f, g, h, i, x, y, z of wave recording device in the valve group ring.

The static reactive power compensation device that the utlity model has monitoring, demonstration, record wave energy has increased following function on the basis of existing technology: current/voltage, electric current and various harmonic wave situation in real-time dynamic monitoring system parameters and the SVC valve group ring, and fault message recorded involve multiple mode and show:

1. online in real time dynamic monitoring display waveform;

2. histogram shows harmonic component amplitude and distribution;

3. the quality of power supply was improved situation and is followed the tracks of governing speed before and after effectively tracing display put into operation;

4. under abnormal conditions, can record ripple such as electrical network fast: flickering; Transition; Peak valley; Fall and SVC valve group ring in fault waveform such as current imbalance;

5. but continuous several times is recorded fault message, and the system power of several cycles before and after the fault, the variation of voltage recollected in record, and fault data is caught in the Pu, and by network and background computer communication, realizes constantly functions such as monitoring and inquiry.

6. harmonic trend analysis and measuring ability are provided.

The beneficial effect that the utility model compared with prior art has is:

Can in the very first time, intuitively understand on-the-spot static reactive power bucking-out system parameter waveform when 1, putting into operation and change, provide foundation accurately to Installation and Debugging, and improved Installation and Debugging speed and reliability.

2, put into operation before and after harmonic wave check and analysis ability improve, make the harmonic component that produces before and after putting into operation very intuitively show amplitude and distribution, and the reasonable configuration filter is effectively administered by histogram.

3, very intuitively the quality of power supply before and after putting into operation is improved effect comparison.

4, the abnormal information in the Apparatus and system have record accurately ripple (comprise time, amplitude, frequency and take place before and after waveform etc.), and quick and precisely provide fault data by this device or background monitoring system, for accident analysis, the quality time is won in repairing fast.
