Sistema na Regulasyon na Pankakasakey na Apoy tan Pantipon

Sistema na panagtipon na enerhiya na bateryaet uusaren ed ngalngalin amin ya lawak na produksyon, pangipapasabi tan panagkonsumo na kuryente. Lapud antikey so panaon na ebat da, maples so kapeles na panag-adjust tan atagey ya inkasusto na panangontrol, mangitarok ira na baleg ya ilalaknab tan inyaligwas ed function o performance ed amin ya lugar na aplikasyon.

Saray Manunan Prinsipyo na AGC ed Thermal Power Units

Say automatic control system parad frequency tan active power ed sakey ya power system et tatawagen ya Automatic Generator Control (AGC). Kaslakan ya ontutukoy iya ed automatikon idarakel o ibawas na target load commands parad saray yunit ya direktan ipapaway na power grid dispatch center panamegley na distributed control system (DCS). Saya so manunan kimey na panagpawala na saray yunit.

Diad silong na premis ya makapawala na atagey-kalidad ya enerhiya na kuryente, say AGC (Automatic Generation Control) et makapenek ed real-time balance na suplay tan pankaukolan na kuryente, tan onkiwas ed saray pananguman na karga ed loob na pigaran minuto anggad samploran minuto, kanian kabiangan itan na segundaryon regulasyon na frequency. Kaiba ed saray manunan kimey to so pamasiansia ed grid frequency ed loob na naabuloyan ya error range, salanti, say frequency error-free adjustment; panangontrol ed net exchange power na interconnected grid pian mankimey unong ed implanon balor; panangontrol ed pansasalat na enerhiya na kuryente na mankokonektaan a grid diad loob na implanon limitasyon; tan pangikoordina ed saray planta na kuryente (unit) ya mibibiang ed remote regulation pian mankimey unong ed prinsipyo na sankaabigan ya economic allocation, pian napalaknab so benepisyo na grid, diad silong na premis ya nasumpal iray limitasyon ed kaligenan na grid, frequency na grid, tan external net exchange power plan, kanian mibibiang ira ed tertiary frequency regulation.

Pian naseguro so ligtas tan malet ya operasyon na sistema na kuryente, wala ray target ya kakaukolanen parad kapasidad tan na-adjust ya kapasidad na saray yunit na panag-generate ya mibibiang ed operasyon na AGC (Automatic Generation Control). Diad sistema na kuryente na China, say rated capacity na saray generating units ya mibibiang ed AGC et kaslakan ya mankaukolan ya mankantidad ira na masulok ya 50% na dagup ya install ya kapasidad na sistema, tan say adjustable capacity na saray generating units ya mibibiang ed AGC et mankantidad na masulok ya 15% na peak load na sistema. Diad espisipiko, parad saray thermal power unit ya mibibiang ed AGC, no say rated power et P, say power regulation range et kaslakan ya 50%P anggad 100%P; say sankatageyan ya power change rate kada minuto et 3%P; say panaon na ebat ed regulasyon na karga et nepeg ya kulang ed 30 segundo; tan parad dynamic regulation error, no alaen so 300MW thermal power unit bilang alimbawa, say regulation error et kulang ed 3MW, tan say sankatageyan ya error et kulang ed 5MW.

 

Say AGC system, a singa nanengneng ed pigura, et manunan tugyopen na AGC controller ed power grid dispatch center, sakey a real-time transmission channel, sakey a remote control unit (RTU), tan say DCS na yunit. Say power grid dispatch center, base ed real-time data nipaakar ed grid load, unit operating status, tan grid frequency, et mangipapawit na saray load ed saray unit, ya manggagawa na AGC commands.

Sarayan ganggan et ipapasabi ed RTU na planta na kuryente panamegley na remote transmission channel, a singa say komunikasyon na carrier. Say RTU et mangipapasabi na saray ganggan na AGC bilang 4-20mA ya signal na kuryente ed DCS na yunit. Say DCS et manguuman ed aktual ya output na kuryente na yunit base ed limitasyon na karga tan saray setpoint na load change rate, ya susubaybayan to ray ganggan na AGC. Diad saman met a panaon, say real-time status na yunit, singa say aktual ya power output, AGC activation status, load tan change rate limits, et nauman ed 4-20mA ya signal na saray transmitter tan ipapasabi ed RTU. Say RTU et manguuman ed real-time status na yunit ed telemetry data, ya ipapasabi ed power grid dispatch center panamegley na remote transmission channel ya uusaren so high-frequency carrier communication. Kanian, say AGC et sakey a remote closed-loop control system parad proseso na produksyon na kuryente, ya ginawa ed computer-based Supervisory Control and Data Acquisition (SCADA) system, sakey a generator set coordination control system, tan sakey a napanmatalkan a tuloy a sistema na pangipasa na impormasyon.

Say regulasyon na AGC tan say kaslakan ya proseso na ebat na sakey a thermal power unit et nanengneng ed pigura:

Bilang sakey a babayaran ya ancillary service ya itatarya na saray planta na kuryente ed power grid, say AGC (Automatic Generation Control) et ireregulate na nanduruman regional power grids panamegley na saray detalyadon totontonen ed pangipaakseb parad grid-connected generation ancillary service management tan grid-connected operation management (ya tatawagen ya "saray duaran totontonen"). Sarayan totontonen so mangiiter na detalyadon totontonen ed kalkulasyon na performance index tan saray paraan na panagsuri parad saray babayaran ya ancillary services, kaiba lay AGC. No alaen so "duaran totontonen" (2019 ya inrebisa ya bersion) parad saray planta na kuryente ed North China regional power grid bilang alimbawa, saray indikasyon na panagsuri parad saray yunit na generator ya mangiiter na serbisyo na AGC et kaiba so profitability index K_Atan say regulasyon ya performance index K_p, no iner si K_pet nipanengneng ed onggendan a pormula:

K_p=K₁×K₂×K₃

Diad pormula:
