WR REACTIVE POWER DOCUMENT 2012

WR REACTIVE POWER DOCUMENT Western Regi on is facing shortage of reactive power resources (for generating & absorbing VARs and dynamic VAR compensation) due to which, line loadability is restricted in some pockets and lines are kept open on high voltage in other pockets, endangering grid SECURITY. To meet the power requirement securely, a lot of 765/400kV lines were commissioned in recent years leading to opening of trunk lines on high voltages during off peak period as the reactive power in the system was much more than necessary. The resources available for managing these high voltages were optimally utilized to keep maximum lines into service. Mai n objective of a power system is to meet the connected load to the maximum extent with the available generation in a secure, economic and reliable manner. The load consists of both active (WATT) and reactive (VAR) components. The transmission of power over AC circuits involves reactive components. The generation of power too contains the reactive participati on. Hence it is important and vital to monitor and control reactive power resources and reactive power consuming elements (sink) to maintain proper voltages in the grid withi n safe and secure limits. Reactive power control thus forms the prime concern of large power grids. The generators absorb and also generate reactive power based on the excitation conditions. To utilize generator’s reactive capability optimally , reactive capability testing was proposed in WR. Accordingly,

NTPC Vindhyachal STPS Unit# 4 was tested on 2424 - 0404 - 2012 successfully. Ot her generators are pursued for testing t o build confidence in Plant Operators. The transmission lines generate VARs under No load or less loaded conditions and consume VARs under loaded conditions. At any given point of time the power system can experience various voltage levels at various locations. In general, under peak load conditions, voltages are high at reactive source points and are low at load points and the direction of reactive power flow is from source to the load, whereas, under the off peak conditions, the reactive power flow is from l oad points to reactive consuming points. The transmission of VARs over transmission elements in peak load conditions further burdens the transmission elements and as a result, the voltages at the load end become further less. Hence it is desirable to meet the reactive power requirement locally and necessary pl anning of reactive compensation to be carried out. Even at nominal frequency and satisfactory voltage operating conditions, voltage collapse cannot be ruled out as voltage is a l ocal phenomenon. This hand book is aimed at bringing out the details of availabl e reactive power resources to help system operators to optimally utilize these resources to maintain voltages profile within IEGC limits in entire Western Region and ensure secure grid operation. Suggestions/comments for i mproving the document are welcome. पिचमी े ीय भार ेषण के6 , मुंबई

REACTIVE POWER CAPABILITY TESTING OF GENERATORS 1. Introduction Generator reactive capability is required to maintain proper system voltage levels, provide appropriate dynamic reserves and assure service reliability. This reactive capability must be validated in a uniform manner that assures the use of realistically attainable values when planning and operating the system or scheduling equipment maintenance. The validation techniques are functional and do not require special instrumentation or procedures. They are designed to demonstrate that the stated capability for the generating equipment can be obtained for continuous operation under expected operating conditions. To meet these requirements, these criteria are established for validating the reactive capability of generating equipment. These criteria define the methods by which ratings are to be established while recognizing the necessity of exercising judgment in their determination. 2. Objectives • To enable declaration of generator reactive power capability, to meet the mandatory requirements

•

To ensure voltage stability

•

To harness benefits in the upcoming ancillary services market to sell reactive power (including sale of dynamic reserves). E. Region should get the market advantage

•

To empower, enlighten and boost the confidence of generating station operators

•

To reduce investments in capacitors, reactors and dynamic VAR devices like SVC, STATCOM etc.

•

To safeguard generators from unsafe operating conditions

3. Regulatory Provisions

The gross and net reactive capability will be determined within the power factor range at which the generating equipment is normally expected to operate as per the following standards / regulations: a) IEGC Part-6; Section 6.6 – Relevant extracts


8/94


(6) The ISGS and other generating stations connected to regional grid shall generate/absorb reactive power as per instructions of RLDC, within capability limits of the respective generating units that are without sacrificing on the active generation required at that time. No payments shall be made to the generating companies for such VAR generation/absorption. b) CEA Technical Standards for Connectivity to Grid, Regulations 2007 – Relevant extracts Part-II Grid Connectivity Standards applicable to Generating Units 1. New Generating Units (1) The excitation system for every generating unit :(a) Shall have state of the art excitation system; (b) Shall have Automatic Voltage Regulator (AVR).

The above performance shall also be achieved with voltage variation of ± 5% of nominal, frequency variation of +3% and -5% and combined voltage and frequency variation of ± 5%. However, for gas turbines, the above performance shall be achieved for voltage variation of ± 5%. c) CEA Regulations -2010 on Technical Standards for Construction of Electrical Plants and Electrical Lines Extracts from Chapter-II, PART-B of the regulations

VOLTAGE CHANGE AT BUS DUE TO REMOVAL / ADDITION OF REACTOR The approximate percentage voltage rise/fall at a Bus due to REMOVAL / TAKING IN of a reactor of capacity ‘Q’ MVAR is:

(Q x 100) ÷ (Fault MVA) Example: Taking in / Removing a 50 MVAR bus reactor at 400kV Kolhapur bus (Short Circuit level of about 6500 MVA and voltage of 410kV), the voltage at the bus would fall / rise by 0.769% i.e. 410x0.769=3.15kV

FERRANTI EFFECT

Sebastian Pietro Innocenzo Adhemar Ziani de Ferranti (April 9, 1864 - January 13, 1930)

A long transmission line draws a substantial quantity of charging current. If such a line is open circuited or very lightly loaded at the receiving end, the voltage at receiving end may become greater than voltage at sending end. 400kV overhead transmission line would generate 55MVAR per 100KM as compared to 2200 MVAR generated by 400kV underground cable.

DIFFERENT TYPE OF LOADS AND ITS REACTIVE POWER CONSUMPTION A great many loads consume not only active but also reactive power. The Industry wise power factor is generally observed to be as follows: INDUSTRY WISE POWER FACTOR(INDICATIVE FIGS) Textiles 0.65/0.75 Chemical 0.75/0.85 Machine shop 0.4 / 0.65 Arc Welding 0.35/ 0.4 Arc Furnaces 0.7 / 0.9 Coreless induction furnaces and heaters 0.15/0.4 Cement plants 0.78/0.8 Garment factories 0.35/0.6 Breweries 0.75/0.8 Steel Plants 0.6 / 0.85 Collieries 0.65/0.85 Brick Works 0.6 / 0.75 Cold Storage 0.7 / 0.8 Foundries 0.5 / 0.7 Plastic molding plants 0.6 / 0.75 Printing 0.55/0.7 Quarries 0.5 / 0.7 Rolling Mills (i.e. ,Paper, Steel , etc.) 0.3 / 0.75

Some typical values of reactive power consumption of individual loads are given below: • Induction motors 0.5 to 1.1 KVAr/KW, at rated output. • Uncontrolled rectifiers 0.3 KVAr/KW. • Controlled rectifiers usually consume much more KVAr/KW than uncontrolled ones and with dependence on the rectifier delay angle. • Arc furnaces around 1 KVAr/KW. पिचमी े ीय भार ेषण के6 , मुंबई

15/94


Both controlled rectifiers and arc furnaces of steel mills have a reactive power consumption characterized by a high average value and fast variations. Purely resistive loads, like filament lamps and electric heaters, do not, of course, consume reactive power. The synchronous motor is the only type of individual load, which can produce reactive power. It consumes reactive power when under excited and produces reactive power when overexcited. Synchronous motors are usually operated overexcited and thus usually produce reactive power.

LOAD VARIATION DUE TO CHANGE IN FREQUENCY/VOLTAGE The –ve dQ/dF suggests that the MVAR demand from the load decreases as frequency rises.
